Sequent Scientific Formulation Scientist Interview: Rounds, Questions and Preparation

What the job involves

A Formulation Scientist in healthcare and pharma develops and optimizes drug formulations, often for generic or specialty products, ensuring stability, bioavailability, and manufacturability. At fast-growing companies like Sequent Scientific, you may work on oral solids, liquids, or topicals, supporting scale-up and regulatory submissions. Day to day involves lab experiments, data analysis, and cross-functional collaboration with analytical and production teams.

Role and Technical Knowledge

1. 1

   What are the key steps in preformulation studies for a new drug candidate?

   Cover physicochemical characterization, solubility, pKa, polymorphism, and excipient compatibility. Mention techniques like DSC, XRD, and HPLC.

2. 2

   How do you select excipients for a tablet formulation?

   Discuss functionality, compatibility, regulatory status, and cost. Include examples like binders, disintegrants, and lubricants.

3. 3

   Explain the difference between immediate-release and modified-release dosage forms.

   Highlight release mechanisms, pharmacokinetic goals, and patient compliance. Mention common polymers used.

4. 4

   What is the role of dissolution testing in formulation development?

   Explain its use in quality control, bioequivalence prediction, and stability monitoring. Mention USP apparatus and media selection.

Practical Scenarios

1. 5

   During scale-up, you observe content uniformity issues in a tablet blend. How would you troubleshoot?

   Consider blending time, particle size distribution, segregation, and equipment parameters. Suggest process optimization and sampling.

2. 6

   A formulation shows poor stability at accelerated conditions. What steps would you take?

   Identify degradation pathways, evaluate excipient interactions, and consider packaging or antioxidant use. Mention forced degradation studies.

3. 7

   How would you approach developing a generic equivalent of a marketed drug?

   Focus on reverse engineering, bioequivalence, and regulatory requirements. Discuss reference product characterization and patents.

4. 8

   You need to improve the bioavailability of a poorly soluble drug. What strategies would you consider?

   Mention particle size reduction, solid dispersions, lipid-based systems, and cyclodextrin complexation. Include in vitro evaluation.

Behavioural and Situational
