Formulation chemists are often tasked with creating products that need to be delivered in specific ways—for example, a skincare product that needs to be absorbed quickly by the skin, or a pill that needs to slowly release its active ingredient over time. By asking about your experience with different types of delivery systems, hiring managers are trying to gauge your versatility and your ability to think creatively about how best to deliver a particular product.

Example: “I have extensive experience in developing formulations for a variety of delivery systems. My work has included oral, topical and intravenous methods.

For oral delivery, I’ve worked on tablet and capsule forms, focusing on aspects like disintegration time, bioavailability, and taste masking.

In terms of topical applications, my focus was on optimizing absorption through the skin while ensuring stability and consistency of the formulation.

Regarding intravenous delivery, I developed solutions and suspensions with careful attention to solubility, sterility, and pH balance.

Throughout all these projects, I adhered to regulatory guidelines and performed rigorous testing to ensure safety and efficacy.”

25. Can you discuss a time when you had to present your formulation work to a non-scientific audience?

A fundamental part of being a formulation chemist is the ability to communicate complex scientific concepts and findings to individuals who may not have a scientific background. This includes presenting to clients, product managers, or marketing teams. Your ability to distill complex information into clear, understandable language is not just a nice-to-have skill—it’s critical. Hence, potential employers want to gauge your ability to bridge this gap effectively.

Example: “During a product launch, I had to explain the new formulation of our skincare line to marketing and sales teams. They needed to understand the benefits and unique selling points but lacked scientific background.

I used simple analogies and visuals to communicate complex chemical concepts. For example, I compared the skin’s absorption process to a sponge soaking up water to illustrate how our product penetrates deeper layers for hydration.

The team appreciated my approach and were able to effectively promote the product by highlighting its innovative formulation. This experience taught me the importance of clear communication in bridging the gap between science and business.”

26. How have you used statistical analysis in your formulation development work?

As a formulation chemist, statistical analysis is a key tool in your arsenal. It allows you to make sense of the data you collect during the formulation process, identify patterns, and make informed decisions about how best to proceed. Employers ask this question to assess your analytical skills and your ability to use statistical analysis to drive the formulation development process. It’s also a way to gauge your problem-solving skills and your ability to make data-driven decisions.

Example: “Statistical analysis plays a crucial role in formulation development. I’ve used it to design and analyze experiments for optimizing formulations. For instance, using Design of Experiments (DOE), I was able to identify key factors that significantly impact the performance of a formulation.

Moreover, regression analysis helped me understand relationships between variables and predict responses. This allowed us to fine-tune ingredients and processing conditions to achieve desired properties.

Furthermore, statistical process control aided in maintaining product quality during scale-up and production. By monitoring critical parameters, we were able to detect trends or shifts in the process early and take corrective actions promptly.

In essence, these tools provided a data-driven approach to decision making, reducing trial-and-error, saving time, and improving product quality.”

27. What strategies do you use to ensure the scalability of your formulations?

The essence of this question lies in the need for practical application of your work. It’s essential for a formulation chemist to not only create effective solutions in a lab setting, but to also ensure that these solutions can be produced on a larger scale without compromising on quality or efficiency. Essentially, the interviewer wants to know if you have the foresight and understanding of the entire development process, from conception to mass production.

Example: “To ensure scalability of my formulations, I prioritize repeatability and robustness. This involves using high-quality raw materials that are readily available in large quantities to avoid inconsistencies during scale-up.

I also employ statistical design of experiments (DoE) for formulation development. This allows me to understand the impact of each component and their interactions on the final product properties, which is crucial when scaling up.

Furthermore, I consider manufacturing processes from the start. By understanding how a formula behaves under different processing conditions, I can anticipate potential issues and adjust the formulation accordingly before it goes into mass production.

Finally, regular communication with cross-functional teams like process engineering and quality control ensures any challenges encountered during scale-up are quickly addressed.”

28. Can you provide an example of a formulation you developed that required innovative thinking?

The essence of a formulation chemist’s job is innovation. Whether it’s creating a new product or improving an existing one, the ability to think outside the box is paramount. By asking this question, recruiters are keen to understand your problem-solving skills, creativity, and how you apply scientific principles to overcome challenges. They want to know if you can bring fresh insights and a unique approach to their team.

Example: “In a project, we were tasked with developing an eco-friendly paint formulation. The challenge was to maintain the same level of performance as traditional paints while using sustainable materials.

I proposed using bio-based solvents and resins, which are derived from renewable resources. However, these materials presented issues in terms of drying time and finish quality.

To overcome this, I innovated by incorporating nanoparticles into the formulation. These particles increased the surface area for solvent evaporation, speeding up the drying process. They also enhanced the binding properties of the resin, improving the finish quality.

This innovative approach resulted in a high-performing, sustainable paint that met all our client’s specifications.”

29. How do you approach the task of developing a formulation that meets both performance and cost targets?

As a Formulation Chemist, balancing performance and cost is often a delicate task. Your potential employer wants to understand your problem-solving skills and your ability to make strategic decisions. They want to see if you can effectively develop a high-performing product while keeping costs within budget. This balance is crucial in maintaining profitability and ensuring the company remains competitive in the market.

Example: “Developing a formulation that meets both performance and cost targets requires a strategic approach. I start by understanding the product requirements, its intended use, and the desired properties.

Next, I identify potential raw materials that can deliver these properties. It’s crucial to consider their availability, cost-effectiveness, and compatibility with other ingredients in the formulation.

Then, I design preliminary formulations and conduct laboratory tests to evaluate their performance. If they don’t meet the required standards, I adjust the composition accordingly.

Throughout this process, it’s important to keep track of costs to ensure the final product is economically viable. By balancing scientific knowledge with practical considerations, an optimal formulation can be achieved.”

30. Can you discuss a time when you had to defend your formulation choices in a peer review setting?

In the dynamic field of formulation chemistry, collaboration and peer review are often key to success. You’re not just creating in isolation; you’re part of a team. That’s why hiring managers want to know how well you can defend and explain your choices. They want to see if you can handle constructive criticism, open to feedback, and have the ability to justify your decisions with solid scientific reasoning. This also shows your communication skills and how effectively you can relay complex information to your peers.

Example: “During a project involving the development of an oral suspension, I had to defend my choice of using xanthan gum as a suspending agent. My peers suggested alternatives like microcrystalline cellulose or sodium carboxymethylcellulose.

I explained that while these agents are effective, xanthan gum provides superior pseudoplastic flow which is crucial for dose reproducibility in oral suspensions. It also has better compatibility with a wider range of preservatives and sweeteners, making it more versatile for different formulations.

This explanation was well received and ultimately, we proceeded with xanthan gum, yielding successful results. This experience underscored the importance of understanding not just how ingredients function, but their interactions within the formulation matrix.”

Formulation chemists are responsible for creating products that meet specific customer requirements, so it is important for them to remember key details about the products they are formulating. Additionally, formulation chemists need to be able to troubleshoot any issues that may arise during the manufacturing process.

Example: “ There are many important things for a formulation chemist to remember, but one of the most important is to always think about the end goal of the product. Formulation chemists need to be able to create products that meet the needs of the customer, and this can only be done if they have a clear understanding of what those needs are. Another important thing for formulation chemists to remember is to always keep up with the latest trends in the industry. This helps them to create products that are in demand and that will sell well. ”

The interviewer is likely asking this question to gauge the Formulation Chemist's understanding of the challenges facing their field, as well as to get a sense of what the Formulation Chemist believes is important. It is important for the interviewer to understand the Formulation Chemist's thoughts on the challenges facing the field in order to assess how the Formulation Chemist would approach these challenges if hired. Additionally, this question allows the interviewer to get a sense of the Formulation Chemist's priorities and what they believe is important in the field of formulation chemistry.

Example: “ There are many challenges facing the field of formulation chemistry, but some of the most important ones include: 1. Ensuring product safety and efficacy: Formulation chemists must ensure that the products they develop are safe and effective for their intended use. This can be a challenge when working with new or untested ingredients. 2. Meeting regulatory requirements: Formulation chemists must develop products that meet all relevant regulatory requirements. This can be a challenge when working with new or untested ingredients or when developing products for new markets. 3. Developing innovative formulations: Formulation chemists must continually strive to develop innovative formulations that meet the ever-changing needs of consumers and businesses. This can be a challenge when working with new or untested ingredients or when trying to improve upon existing formulations. ”

There are many things that are important for a student of formulation chemistry to remember, but one of the most important is the need to be able to understand and apply the principles of chemistry to the development of new products. Formulation chemists must be able to understand the chemical properties of the substances they are working with and how those properties can be manipulated to create new formulations. They must also be able to develop new methods for manufacturing and testing these products.

Example: “ There are many things that are important for a student of formulation chemistry to remember, but one of the most important is the need to be able to understand and apply the principles of chemical thermodynamics. This includes understanding concepts such as entropy, enthalpy, and free energy. Additionally, it is important to be able to use these concepts to solve problems related to the formulation of chemical products. ”

There can be a few reasons why an interviewer would ask this question to a formulation chemist. One reason could be to gauge the level of experience and knowledge the chemist has in the field. Formulation chemistry can be a complex and detailed field, so it is important for researchers to have a strong understanding of the various concepts and principles involved. Additionally, this question could be used to assess the chemist's ability to think critically about the research process and identify key areas that need to be focused on in order to produce successful results.

Example: “ There are many important things for a researcher in formulation chemistry to remember, but one of the most important is to always be aware of the potential for chemical reactions. Formulation chemistry involves working with a variety of chemicals, and it is important to be aware of how these chemicals can interact with each other. This knowledge can help researchers avoid dangerous situations and create more effective formulations. ”

There are a few possible reasons why an interviewer might ask this question to a formulation chemist. One reason could be to gauge the chemist's understanding of the formulation process and the importance of various factors in creating a successful product. Another reason could be to see if the chemist is able to prioritize and identify the most important elements of their work. This question could also be used to assess the chemist's problem-solving skills, as they would need to weigh the importance of various factors in order to come up with a answer.

The most important thing for an industrial chemist working in formulation chemistry to remember is that the process is iterative and that each step builds upon the previous one. In order to create a successful product, it is essential to have a strong understanding of the ingredients being used and how they interact with each other. It is also important to be able to troubleshoot any problems that may arise during the formulation process.

Example: “ There are many important things for an industrial chemist working in formulation chemistry to remember, but one of the most important is to always be aware of the potential hazards involved in working with chemicals. Industrial chemists must always follow safety procedures and take precautions when handling and using chemicals, as even small amounts of some chemicals can be dangerous. ”

An interviewer would ask this question to gauge the Formulation Chemist's understanding of the role of a government regulator in overseeing the formulation of chemicals. It is important for a government regulator to remember the potential hazards of the chemicals being regulated and to ensure that they are properly labeled and stored.

Example: “ The most important thing for a government regulator of formulation chemistry to remember is that the safety of the public is always the top priority. Formulation chemists must always ensure that the products they develop are safe for use by the general population, and that any potential risks are properly assessed and managed. ”

The interviewer is asking this question to gauge the Formulation Chemist's understanding of the product and its importance to the public. This question is important because it allows the interviewer to understand how the Formulation Chemist views the product and its importance to the public.

Example: “ The most important thing for a member of the public who uses products containing formulations to remember is that they should always read the label carefully before using the product. This will ensure that they are using the product correctly and safely. ”

There are many important things to remember when learning about formulation chemistry, but one of the most important is to understand the basics of chemical reactions. Formulation chemists need to be able to understand how different chemicals interact with each other in order to create the desired effect. Without this understanding, it would be very difficult to create effective formulations.

Example: “ There are many important things to remember when learning about formulation chemistry, but one of the most important is to understand the basics of chemical reactions. This includes understanding reactants, products, and catalysts and how they interact with each other. Once you have a firm grasp on these concepts, you can begin to learn more about specific formulations and how to create them. ”

Formulation Development Scientist Interview

Modern Medicine wouldn’t be where it is today if not for the final medicinal product (tablet, pill, capsule, lotion, creams etc) that is not only stable in real world conditions but also acceptable to patients in dosage and form.

Om Shelke (PhD), our next pathbreaker, Formulation Development Scientist, develops drug products for Semisolid/Topicals/ Dermatology Formulations so that a suitable and stable dosage can be easily administered to patients.

Om talks to Shyam Krishnamurthy from The Interview Portal about working on a range of formulations to administer health products to meet different needs; and interesting challenges he faced in the development of new formats for oral care.

For students, formulations are playing an increasingly important role in the world of medicine through newer and effective ways to administer drugs. Focus on better technologies to improve drug efficacy.

Om, tell us about your background?

I was born and brought up in a big (22 people) joint family where we used to run so many businesses in our village. We used to have a monopoly in the village: whatever you wanted to buy, you could buy from us and whatever you wanted to sell, you could sell us.

I was completely involved in business activities, in fact, I wanted to be a cricketer. I used to play very good cricket and always used to lead our cricket team. In our village, we had school till 7th standard only. When I completed 7th standard, the teacher told my parents that since I was a bright student, they should send me to the district for further schooling. Actually, this is the moment which transformed my business mind to focus on other opportunities.

I completed my education till 12th Standard from the district. I moved to Pune which was completely new for me. The interesting part is, when I used to talk in Pune, people used to recognize me as being from Marathwada. I took that opportunity to learn the language of Pune so that nobody could judge where I was from.

What did you do for graduation/post-graduation?

I have completed my BPharm and MPharm from the University of Pune

I then started preparation for the GATE(GPAT) Exam which is mandatory if you want to pursue MPharm along with a stipend. My hard work and luck led me to qualify for the GATE(GPAT) Exam for which I got the 8000 Rs per month stipend throughout the MPharm programme. I was very fortunate to have good seniors in my college, they guided me very well. I would like to acknowledge two of my seniors, Kunal Sable and Rohit Shirode. They played a very important role in my academic journey, helping me and guiding me through every step.

I also did my PhD in Pharmacy, Pharmaceutical Sciences, and Administration from Pacific University, Udaipur.

What made you choose such an offbeat, unconventional and uncommon career?

I was very passionate about research in the pharmaceutical field. What attracted me to this noble profession was the ease with which medicines relieve the pain or discomfort of a person.

I was not willing to do the MPharm unless I got through the GPAT exam. If I didn’t get through, I had decided to work as a teacher in a pharmacy college, so that I would get sufficient time to study and reappear for the GPAT exam. Fortunately, I got through the exam in my first attempt only. Based on my GPAT scores, I got admitted for MPharm. During MPharm, I decided to enter into the industry.

How did you plan the steps to get into the career you wanted? Tell us about your career path

I started looking for my industrial project internship after completing my first semester in MPharm. It took a lot of effort to search for an industrial project in the second year of my MPharm. Though I had very limited contacts in the industry, I tried very hard and approached all seniors and teachers. I applied at so many places but received no responses from companies because one needed a strong reference to get an industrial project. After applying to so many places I got an industrial project in Glenmark research center through my senior Rohit Shirode. This was the breakthrough I needed to enter into the industry and I took this golden opportunity very positively. My senior colleague (Ashish Rane) always used to tell me to work hard here. I worked very hard on my project as well as company projects. Generally, trainees do not get an opportunity to work on company projects, but fortunately, I got this opportunity.

In Glenmark, I started as a project trainee for 9 months. Generally, the project needs to be finished within 6 months; but I could not finish in 6 months as I was also working on company projects which were of higher priority than my projects. The project got extended by 3 months, which was a big turning point in my career and i got a break as an employee in Glenmark as Research Associate. I worked for 3 years in Glenmark research and development Centre for the US FDA Market.

As an intern, I started working on the tablet which is used in the treatment of Cardiac Arrhythmia. It was a high priority project and almost two teams of scientists (6 scientists) were working on the project to meet the timelines. We failed 14 times to meet the bioequivalence studies on actual human volunteers but succeeded in the 15th study. Another project in which I had worked on was the antimalarial suspension.

I learned based on my experience; I would help my superiors to finish some of their work which would not only help them but was equally beneficial for me as well, as I was learning the work of my superior one level up in the organization. Similarly, my superiors helped their superiors, in this chain everybody was getting exposed to the work of one level above their position. This will help a person grow in their organization professionally and financially.

I worked with the Glenmark Research Centre for three years. I used to develop medicated products for the US market. The important aspect about myself is, I never say no to any work. If you know how to do the work, it will increase your perfection, and if you do not know, it’s a great opportunity for you to learn. This has increased my knowledge in my professional life.

I moved to Dr. Reddy’s Lab in Aug 2015 as a Formulation Scientist for the development of semisolid products for USFDA. The culture and the professional environment in Dr. Reddy’s Lab shaped my professional etiquettes and behavior. There I learned how to portray my work to higher management. Basically, everybody should know how to portray their work in a good way, presentation of work is very important in order to pass the project stages.

Actually, I wanted to enter the industry after completion of my PhD, but fortunately I got a job immediately after completion of my internship during my MPharm project. Amongst the 12 interns, I was the only one who got selected for the job after 5 rounds of interview. During my internship I worked very hard. This helped me a lot in building my practical experience and hands-on knowledge of each equipment and instrument. Then I decided to pursue a PhD while working, which requires a lot of dedication and effort. For those who want to achieve something in life, life always makes way for them. It took me 4 years to complete my Phd while working. It was not easy to finish the research work and do my thesis while working, it took lots of effort and sacrifices. I had been working more than 18 hours to complete my PhD research and thesis.

To get a PhD was my dream and I approached one of my teachers, who was a principal in a Pharmacy college. He was a very good human being. He introduced me to my PhD supervisor and we had a very good discussion about the project plan. He was registered as a supervisor at Pacific University. Generally, students choose the university first and then the supervisor, but it was reverse in my case. The university announced the test exam for PhD students in December 2014. I got through the PhD entrance test and presented my research proposal to the committee; the committee liked the research proposal. They approved the research proposal and I finally got admitted for PhD in March 2015 .

My Ph.D. thesis was based on the development of “Emulgel” (When gel and emulsion are used in the combined form, they are referred as Emulgel) product by using the concept of Quality by Design. In pharmaceutical industries, the testing is done after the product is manufactured, but the Quality by Design concept ensures that quality is built inside the product through tests to ensure the product is meeting the predefined specifications. I developed the Emulgel product which has better antifungal efficacy than the currently marketed product. I have done animal studies for antifungal efficacy on mice. It was very critical to get approval for animal studies. To perform animal study, the study protocol should be approved by the Control and Supervision of Experiments on Animals (CPCSEA) and the Institutional Animal Ethics Committee (IAEC). It took me 3 years to finish the research work and half a year to complete the thesis typing. I have presented my thesis work to my supervisors and to another professor as pre-viva. Then I submitted my thesis after the approval of my supervisors. It took 3-4 months for them to review the thesis and arrange the final viva. I successfully defended my Ph.D. viva in July 2019 and officially became Dr. Om Shelke.

In Dr. Reddy’s Lab, I had worked on 505 b2 (NDA) products. These types of products are different from what is available in the market. Though a new product could be for a new disease or same disease, the formulation will be different to meet the patient’s needs. If patients are using the drug as a tablet, the same drug can be used for some other disease in the form of cream. I have changed the route of administration of the drug which was previously used in the form of tablet into cream by developing this formulation. I was the first one in the department, who developed the product within one year and successfully completed the toxicology studies on pigs. I then transferred the project from R & D (10 Kg batch size) scale to commercial production site (500 Kg batch size). Now that product is being successfully marketed in the US market.

To support my wife’s education as she was studying in Mumbai, I switched to Abbott India. In 2017 Abbott was the top pharmaceutical company in India. It was a proud moment to work with India’s top ranked company. There I developed projects for the Indian market. The biggest difference between working for the US market and the Indian market is the satisfaction of seeing the product developed by you, helping your relatives, friends, and family to relieve their pain or discomfort. This gives immense work satisfaction because we are helping our own community. In my past career, I launched so many projects but couldn’t see the benefit of the products as they were all launched in the USA.

In Abbott, I worked on the development of differentiated formulations. Differentiated formulation means a formulation that is modified in such way that it will be very easy for the patients to apply. There was a cream product available in the market, but creams are oily and difficult to apply on the back side of the body. We developed a formulation as lotion (Liquid) from the cream (semisolid) which allows patients to apply it comfortably on all parts of the body and skin. I have developed a range of medicated shampoos for use on a daily, weekly and biweekly basis for dandruff. We have also developed an applicator to insert the gel product in the anus to make it easier for patients to apply and feel comfortable when they use the medicine.

In 2018, I got an opportunity to work with Hindustan Unilever, which is a subsidiary company of Unilever industries. Unilever is the world’s top company and is present in almost all segments. Probably, everyone starts their day with Unilever products and ends their day with Unilever products such as Pepsodent, Close-Up, Knorr, Kwality Walls, Brookbond, Lifebuoy, Fair and Lovely, Rin, Tide, Pure-it and so many other brands.

In Unilever, I worked on Oral care products such as Pepsodent and Close-Up. I was involved in the development of new formats for oral care. Traditionally, we have always used powder (ash powders) for cleaning the teeth and mouth. Since toothpaste has been invented people have been using toothpaste for maybe the last 100 years. We never thought of an alternative to toothpaste, though in Unilever, we have developed a tablet for brushing. Instead of carrying the toothpaste, you just need to carry the tablet and crush the tablet in your mouth and start brushing. Spit out the residue after brushing and rinse the mouth with water 2-3 times. Why brushing tablets? Brushing tablets are made from powdered toothpaste that’s condensed into tablets. They’re small and solid, more closely resembling a pill than a paste. They can be packaged and shipped in recyclable glass or paper containers, negating the need for tubes—which are often made from a combination of plastics and aluminum. Generally, 70 % of water is used for the manufacturing of toothpaste as well as brushing with the toothpaste and for mouth rinsing (Approximately 10-12 rinsing). However, brushing tablets are water-free and require less water for mouth rinsing (approximately 3-4 rinsing). So ultimately we are saving a large quantity of water which results in a lower carbon footprint. Since they’re solid, they’re also travel-friendly, and the tablet size ensures the optimum amount of paste with every brushing. I have worked on oral care products to make them preservative-free without impacting the microbial stability of the products. Unilever is the best place to work for those who are willing to grow three-dimensionally (Professional, financial and personal). Loop was an interesting project launched by TerraCycle based on sustainability and reducing the carbon footprint in the UK. One of the products which I developed was the part of it. Loop by TerraCycle was based on the concept of using the product, returning the containers, and reusing the containers.

How did you get your first break?

My first break was through an industrial project in Glenmark Research Center through my senior Rohit Shirode. This was the breakthrough I needed to enter the industry and I took this golden opportunity very positively. This turned into a full-time job before my PhD.

What were some of the challenges you faced? How did you address them?

Adapting to the work culture was very difficult for me; since research work does not have time limits, sometimes I had to work more than 18 hours to meet the deadlines, and fortunately or unfortunately, I was working on a high priority project. So working continuously for more than 18 hours was very difficult for me. Sometimes we ate food late and sometimes we ate no food at night. But I was willing to learn and it was a great opportunity for me to work on such a project. If you are ready to do hard work, you will be happy to do work.

Adjusting with the professional culture was another challenge for me. I was exposed to only an academic background; I knew only about academic life. But I overcame this challenge by undergoing training on Professional Etiquettes and Behaviour. This helped me in building my confidence in handling professional situations.

Where do you work now? Tell us about your role

One fine day in 2019, I received a call for an international opportunity in research and development. I have always wanted to pursue an M.S. from foreign universities, but due to lack of finances and proper guidance, I was not able to apply to foreign universities. After an interview and completing the formalities, I got recruited and received a visa for Hong Kong in 2019. Since then, I have been working in Hong Kong as a Formulation Development Scientist in Bright Future Pharmaceuticals Lab Ltd. Adjusting to the new culture in a new organization is very difficult, especially with the Chinese companies as they don’t prefer to talk in English and that’s the only language through which we can communicate with them. We need to be more proactive in planning and performing the work tasks.

What is your role as formulation development scientists?

Formulation scientists develop a drug product that may be in solid, liquid, or semisolid form such as a tablet, suspension, or cream. Basically, we convert the drug molecule into the form so that a suitable stable dosage can be easily administered to the patient to travel inside the patient’s body. The drug should be stable inside the product. We need to study the drug properties extensively to understand the drug behaviour in different chemical compositions and under different storage conditions. Based on drug molecule stability and the intended clinical action, we decide which formulation is suitable for the drug. Then we select the different chemicals called excipients or ingredients to stabilize the drug in the drug product. We study the stability of each chemical composition as per the ICH guidelines and select the stable formulation composition amongst them. The stable formulation is studied for the in-vitro models. Sometimes extensive animal studies also need to be done on actual animals such as rats, mice, rabbits, or pigs. What are the in-vitro models? In-vitro models are the tools through which we can create a similar condition like in our body, in the instrument artificially and complete testing. After doing the in-vitro studies, the study will be performed on actual human volunteers and the final formulation is selected. Then that will be transferred to the commercial production site. All the study data will be submitted to the drug regulatory agency of respective countries. After reviewing the data, if everything is okay, the regulatory authority will give the marketing authorization, and subsequently, it will be launched in the market.

The typical day will be like, coordinating project activities with cross functional teams, performing development activities in the lab, attending the project meetings, and planning future activities. Most of the time in a day will be spent in the lab with different activities. Sometimes, we also need to search literature extensively to resolve the issues associated with projects. It is always hard to coordinate with the cross functional teams and get the work done from them.

Tell us an example of a specific memorable work you did that is very close to you!

Developing products for the Indian market is closer to my heart because you can see the output of your work. I have developed one product for the Indian market and that was a transparent gel. When I was discussing with the supplier who had discovered these excipients, he told me that transparent gel with these excipients is not possible. But I made it possible with my efforts. This innovation was a bit challenging and I always like to take on challenges. I am always happy to stress myself to the extreme and achieve something which is difficult.

How does your work benefit society?

I personally feel I am in a noble profession of helping people who are suffering from pain or discomfort in life. The medicines either cure the pain or discomfort associated with the patients. Actually, medical practitioners get all the credit for their treatment but the ones who actually invented or manufactured the medicine, don’t get the right credit for the treatment from society. In Spite of this, we are bound to invent or manufacture medicine for the good of society.

Your advice to students based on your experience?

There is no alternative for hard work, of course. Though I believe in luck also, if you do the hard work, you will get the fruits one day. It might take a while, but you will definitely get it. Planning your future is the most important thing if you want to have a great future. It is better to plan everything in advance to execute in a better way. Though there may be some deviation, the goals should be fixed. Strong determination will lead to success.

Future Plans?

I personally believe in learning; I have always wanted to learn things that will help me in building my future career. Recently, I have completed an executive MBA course through distance learning in Oct 2020. Now I got admitted for another course in Regulatory affairs, this will help increase my future opportunities for a higher position. Everybody should build their knowledge so they can grow in their career.

Forecasting is very important in the professional as well as personal life, this will lead to planning your life very well. Regarding future planning, I want to be a good leader in the pharmaceutical field. In order to achieve that vision, I have done my MBA, and now pursuing a course on Regulatory Affairs. I would also like to pursue a course in Intellectual property rights.

Research and Development Interview Questions

Let us learn about common research and development interview questions.

What Are Research and Development?

As the name suggests, research and development (R&D) is a systematic way of developing new products, processes, and services .

R&D is not restricted to industries like pharmaceuticals or chemicals; it can be helpful to any field of work. Most companies conduct R&D to introduce the latest technology to their products.

Research is the term used for studying or analyzing something without any intention of implementing or producing results.

Development, on the other hand, is the process of transforming research findings into actionable items.

As soon as a company identifies a need for its product, it starts research to find out what customers are looking for and if their existing product can be improved upon.

Some companies conduct primary research, which includes surveys and interviews with the customers. The findings from such research help the company design a product.

Is It a Good Career?

A career in R&D is an excellent choice for people who are passionate about science and want to contribute to making the world a better place.

People in this field get to work on multiple technologies and find solutions to complex problems. The work environment is less stressful than other careers, and there are fewer chances of getting laid off.

As compared to other professions, the pay is not high enough, but if you’re interested in research, it can be a fulfilling career.

Research and Development Interview Questions

The interviewer may ask common R&D interview questions like:

What fuels your competitive drive at work?
How do you react to tight deadlines?
What motivates you to continue working on a project after it has been rejected?

7 Leading Interview Questions for R&D Candidates

If you’re looking to hire an R&D professional, we have the rundown on the best research and development interview questions to ask during your next hiring cycle. An R&D role involves the innovation, introduction and improvement of products and processes — so a great hire can truly propel your company forward.

Explain how you have used research methods in prior roles.

You can follow this up by asking, “What tools or programs would you need at your disposal on Day One of this role in order to succeed?” Dig deep to find what research methods (and even specific technology) the candidate has used to make products or processes more efficient.

In your opinion, which is the better approach: Working quickly to develop a good solution or taking more time to craft an excellent solution?

This is one of the top research and development interview questions, as it reveals how the candidate performs under pressure. Much of the role involves working under deadlines. But how does the quality of the work match up to those pressures? This question will help you discover if the candidate can balance various factors, such as time-sensitivity and quality of results.

Elaborate on the most challenging project you have worked on. What challenges are you looking for in this role with our company?

An excellent R&D professional would never wish to remain stagnant or avoid challenging projects and situations. This question will clue you in to the intensity of projects the candidate has completed, as well as any aspirations to grow he or she may have.

What do you know about our company, and what would you bring to the table in this role?

All candidates should have researched your company. It’d be laughable any other way — a research and development professional showing up to the interview without any research. Does he or she have any improvements in mind for your company? Top-tier R&D professionals are especially astute at formulating better and better ideas and products. Thus, the candidate should have some fresh ideas to bring to the interview based on his or her research about your business.

Have you ever faced difficulties in convincing others of your own ideas? What did you do to get them on board?

This is one of the best research and development interview questions, as it reveals the candidate’s leadership style and ability to promote ideas before bringing them to fruition. How does he or she go about informing team members or other departments (see below) of blueprints for a great project? What happened after convincing fellow employees your idea was valid?

How would you cooperate with other departments? Which other departments would be most crucial for your work, or would influence your role most?

How effectively does the R&D candidate work with other teams and departments to achieve goals? This question is a must. You can also conduct a reference check following the interview to see how the candidate fared with other coworkers. A research and development professional shouldn’t just work solo; collaboration is essential to creating a positive culture and fostering positive business results.

What other research and development interview questions would you add to this list? Let us know — and contact the professionals at Y Scouts when hiring for R&D roles.

17 Research And Development Director Interview Questions and Answers

Learn what skills and qualities interviewers are looking for from a research and development director, what questions you can expect, and how you should go about answering them.

Research and development directors are responsible for planning, directing, and coordinating research and development activities within an organization. They also work with other departments to ensure that research and development activities are aligned with the organization’s business objectives.

If you’re looking for a job as a research and development director, you’ll need to be prepared to answer a variety of interview questions. In this guide, we’ll provide you with sample answers to some of the most common research and development director interview questions.

Are you familiar with the latest developments in your field of research and development?

What are some of the most important qualities for someone in a leadership role within the r&d department, how would you go about developing a long-term strategy for the r&d department, what is your process for selecting and training new researchers for your team, provide an example of a time when you had to deliver bad news to upper management about a failed product trial., if hired, what would be your top priority as a research and development director, what would you do if you and your team were working on two separate projects that could potentially be combined into one, how well do you handle stress and pressure, do you have any experience working with budgets for r&d projects if so, how did you prioritize spending, when hiring new employees, what is your process for assessing whether or not they would be a good fit for your team, we want to improve our customer service. how would you go about researching best practices for customer engagement, describe your process for ensuring that all of your team’s work is aligned with the company’s overall goals., what makes you the best candidate for this research and development director position, which industries or companies do you admire the most for their use of r&d, what do you think is the most important thing to remember when working on new products or services, how often do you update your knowledge and skills as a research and development director, there is a lot of competition in the industry for new products and services. how would you motivate your team to stay focused on innovation.

This question can help the interviewer determine your level of expertise in your field. It’s important to stay up-to-date on new developments and advancements, as this shows you’re passionate about your work and want to continue learning more. When answering this question, it can be helpful to mention a few recent discoveries or innovations that have inspired you.

Example: “I’m always looking for ways to improve my research methods and processes. Recently, I read an article about how some companies are using virtual reality technology to test their products before they go into production. This got me thinking about how we could use similar technology at our company to create better products. I think implementing these types of strategies would benefit both our customers and our business.”

This question can help the interviewer get to know you as a leader and how you would approach your role in this position. Use examples from your past experience or other qualities that you feel are important for someone in this role.

Example: “In my opinion, one of the most important qualities for a research and development director is being able to communicate effectively with others. I’ve found that it’s helpful to be open-minded when receiving feedback on ideas and projects. It’s also important to have an understanding of what each team member does within the department so you can provide support where needed.”

The interviewer may ask you this question to gauge your strategic planning skills and how they can be applied to the company. Use examples from past experiences where you developed a long-term strategy for an R&D department or similar role, and explain how it helped you achieve success in your previous roles.

Example: “In my last position as research director at XYZ Company, I worked with senior management to develop a five-year plan that outlined our goals for the next few years. We used this plan to help us prioritize projects and allocate resources to ensure we met our deadlines. This process also allowed me to work closely with other departments to identify areas of improvement and create solutions.”

This question can help the interviewer understand your leadership skills and how you manage a team. Your answer should include information about what steps you take to ensure new researchers are trained in their roles, as well as how you select candidates for open positions.

Example: “I start by reviewing our current staff members’ skill sets and identifying which ones we need more of. I then look at our budget to see if there is funding available for training or hiring new employees. Once I have identified potential candidates, I meet with them one-on-one to discuss the position and learn more about their background and experience. If they seem like a good fit, I bring them into the office to meet the rest of the team and give them an overview of the company.”

Interviewers may ask this question to assess your ability to communicate with others and how you handle failure. In your answer, try to highlight your communication skills and emphasize that you can take responsibility for failures.

Example: “In my last role as a research and development director, I had to inform upper management about the failure of a product trial we were conducting. The company was developing a new type of software that would allow users to stream music from their phones without using data. However, after testing it in our target market, we found that many customers didn’t like the idea of having to use an app to listen to music on their phone. We ended up canceling the project.”

This question is an opportunity to show the interviewer that you have a plan for how you would approach your role as research and development director. Your answer should include a specific example of something you would do or change in your first few months on the job.

Example: “My top priority as research and development director would be to create a more efficient workflow within my team. I believe this can be achieved by implementing new software programs, which will allow us to communicate better with one another and share information more quickly. This will help me assess each member of my team’s strengths and weaknesses so we can assign projects based on their individual skill sets.”

This question can help the interviewer determine how you handle multitasking and prioritize projects. In your answer, explain what steps you would take to evaluate both projects and decide which one is more important to complete first.

Example: “If I were working on two separate projects that could be combined into one, I would start by evaluating each project’s budget, timeline and goals. Then, I would meet with my team to discuss our options for combining the projects. If we decided it was best to combine the projects, I would work with my team to create a new timeline and budget for the combined project. Finally, I would communicate this change to all stakeholders involved.”

Research and development directors often have to make important decisions quickly. They also need to be able to handle stress well, as they may work long hours in a fast-paced environment. When answering this question, it can be helpful to mention how you’ve handled stressful situations in the past.

Example: “I find that I do my best work when under pressure. In fact, I prefer working late nights or on weekends if it means getting an assignment done before a deadline. I know that some people don’t like working under pressure, but for me, it’s motivating. I feel like I perform better when there is a lot at stake. I think I would thrive in this role because of this.”

The interviewer may ask you this question to understand your experience with budgets and how you prioritize spending. Use examples from past projects to explain how you determined which R&D projects were most important to spend money on, and how you managed the budget for those projects.

Example: “In my last role as a research and development director, I had to create an annual budget for all of our R&D projects. I started by determining what percentage of the company’s revenue we could allocate to R&D projects. Then, I prioritized projects based on their potential impact on the company’s bottom line. For example, I would give more funding to projects that increased sales or reduced costs.”

Hiring new employees is a big responsibility for research and development directors. They need to ensure that the people they hire are going to be able to contribute to their team in meaningful ways. This question allows you to show how you assess potential candidates and determine if they would be good fits for your company.

Example: “I always start by looking at each candidate’s resume, but I also like to meet with them one-on-one to get a better idea of who they are as individuals. During this meeting, I ask about their previous work experience and what they hope to gain from working here. I want to make sure that we’re hiring someone who will fit into our culture and add value to our team.”

This question can help the interviewer understand your research skills and how you apply them to real-world situations. Use examples from previous projects or experiences that highlight your ability to conduct research, analyze data and implement changes based on what you learn.

Example: “I would start by researching customer engagement best practices in general. I’d look at other companies’ approaches to customer service and see if there are any similarities between their strategies and ours. Then, I would evaluate our current customer service strategy and compare it to these best practices to determine where we could improve.”

The interviewer may ask you this question to understand how you plan and manage your team’s work. Your answer should show the interviewer that you can use a variety of tools and techniques to ensure all projects are on track, within budget and meet company goals.

Example: “I start by reviewing our strategic plan every quarter to make sure I know what we need to accomplish in the next year. Then, I review each project my team is working on to see if it aligns with the overall goals of the company. If not, I redirect the project so that it does. This process helps me keep everyone focused on the most important tasks while also allowing us to take on smaller projects as needed.”

This question is your opportunity to show the interviewer that you are qualified for this role. Use examples from your experience and education to highlight your skills, knowledge and abilities.

Example: “I am a highly motivated individual who has proven my ability to work well with others. I have excellent communication skills and can collaborate with teams of all sizes. My attention to detail and problem-solving skills make me an ideal candidate for this position. I also have extensive research and development experience in various industries, which makes me a valuable asset to your company.”

This question can help the interviewer get a better sense of your experience and how you apply it to your work. Use this opportunity to highlight some companies that have inspired you or whose products you use yourself.

Example: “I admire Apple for their ability to create innovative products while still maintaining an aesthetically pleasing design. I also really like Amazon’s approach to R&D because they’re constantly looking for ways to improve their customer service, which is something I’m passionate about as well. In my last role, we were able to implement several new features into our software based on feedback from customers.”

This question can help the interviewer get a better idea of your research and development skills. Your answer should include examples from previous projects that highlight your ability to create new products or services, as well as how you manage teams to do so effectively.

Example: “I think it’s important to remember that every project is unique in its own way. I always make sure to take time at the beginning of each project to understand what my team members’ strengths are and how we can use them to our advantage. This helps me develop strategies for managing different types of projects and ensures that we’re able to meet deadlines while still producing high-quality work.”

This question can help interviewers understand how you stay up-to-date with industry trends and technology. Your answer should show that you are committed to learning new things, whether through formal education or self-study.

Example: “I am always looking for ways to improve my skills as a research and development director. I have taken several online courses on topics like project management and business strategy. I also subscribe to several publications that discuss the latest developments in technology and innovation. In addition, I attend conferences and seminars where I can learn from other professionals.”

This question can help the interviewer understand how you would motivate your team to innovate and create new products. Use examples from past experiences where you motivated your team to stay focused on innovation and creativity.

Example: “I believe that innovation is a process, not an event. I have found that it’s important to keep my team members motivated by celebrating small wins along the way. For example, when we were developing our last product, we celebrated every time we met one of our milestones. This helped us feel more accomplished as a team and kept us motivated to continue innovating.”
