Datar Cancer Genetics Formulation Scientist Interview: Rounds, Questions and Preparation

What the job involves

A Formulation Scientist in healthcare and pharma develops and optimises drug formulations, from pre-formulation studies to final dosage forms such as tablets, capsules, or injectables. At fast-growing companies like Datar Cancer Genetics, you may work on oncology or diagnostics-related formulations, running lab experiments, analysing stability, and supporting scale-up under regulatory guidelines. Day to day involves preparing samples, recording data, troubleshooting formulations, and collaborating with analytical and clinical teams.

Role and Technical Knowledge

1. 1

   What are the key steps in pre-formulation studies for a new drug candidate?

   Cover physicochemical properties like solubility, pKa, polymorphism, partition coefficient, and compatibility with excipients. Mention how these guide dosage form selection.

2. 2

   How would you approach formulating a poorly soluble anti-cancer drug for oral delivery?

   Discuss techniques like particle size reduction, solid dispersions, lipid-based systems, or cyclodextrin complexation. Link to improved bioavailability and targeted release.

3. 3

   Explain the difference between immediate-release and modified-release tablets. When would you choose each?

   Define release profiles and give examples of patient needs or drug properties that favour one over the other. Mention regulatory and stability considerations.

4. 4

   What is Quality by Design (QbD) and how does it apply to formulation development?

   Explain QbD as a systematic approach starting with quality target product profile, critical quality attributes, and design space. Mention risk assessment and design of experiments.

Practical Scenarios and Lab Problems

1. 5

   You observe capping during tablet compression. What could be the causes and how would you troubleshoot?

   List causes like poor granulation, insufficient binder, high compression speed, or tooling issues. Suggest fixes such as adjusting moisture, binder concentration, or compression force.

2. 6

   A formulation shows a degradation peak in stability studies at accelerated conditions. What steps would you take?

   Outline investigating the degradation pathway, checking excipient compatibility, adjusting pH or antioxidants, and confirming with analytical methods. Mention ICH stability zones.

3. 7

   How would you scale up a lab-scale tablet formulation to a pilot-scale batch?

   Discuss maintaining similar granule properties, using scale-up rules like constant power or force, and monitoring critical parameters. Highlight documentation and GMP compliance.

4. 8

   If an injectable formulation shows precipitation upon storage, what could be the reason and how would you resolve it?

   Consider pH shifts, solubility limits, or excipient interactions. Suggest reformulation with co-solvents, surfactants, or lyophilisation, and re-evaluate stability.

Behavioural and Teamwork Questions

1. 9

   Describe a time you worked in a team to complete a lab project under a tight deadline.

   Use STAR format to show planning, role division, communication, and outcome. Emphasise adaptability and learning from setbacks.

2. 10

   Tell me about a mistake you made during an experiment and how you handled it.

   Be honest about a minor error, focus on corrective action, documentation, and what you learned to prevent recurrence. Show accountability.

3. 11

   How do you handle repetitive tasks like sample preparation while maintaining accuracy?

   Highlight discipline, use of checklists, attention to detail, and understanding the importance of each step for final product quality.

4. 12

   Why do you want to work in a fast-growing company like Datar Cancer Genetics rather than a large established pharma?

   Express interest in oncology, faster decision-making, broader learning, and direct impact. Connect personal goals to the company's focus on cancer diagnostics and therapeutics.

HR and Career Motivation

1. 13

   What attracted you to the role of Formulation Scientist in oncology?

   Link personal motivation to improving cancer treatment, interest in novel drug delivery, and desire to work at the interface of research and patient impact.

2. 14

   Where do you see yourself in three years in this role?

   Show realistic growth: gaining expertise in formulation, contributing to IND filings, or leading a small project. Mention learning regulatory and scale-up aspects.

3. 15

   How do you stay updated with recent trends in pharmaceutical formulation?

   Mention journals like AAPS PharmSciTech, regulatory guidelines, webinars, and online courses. Show curiosity about new excipients or delivery technologies.

4. 16

   Are you comfortable working in a lab environment with strict safety and documentation protocols?

   Confirm yes and give examples from academic labs of following SOPs, wearing PPE, and maintaining records. Emphasise reliability and attention to detail.
