Likely interview questions for this role

Written from this job description, not a generic list. Each one notes what the interviewer is really checking.

About your past

Tell me about a technology transfer to an internal site or third-party manufacturer that ran into trouble. What happened and what did you do?

What they are checking: Real tech transfer experience and how problems are handled with partner sites.

Tell me about a time analytical development and your formulation team disagreed on what the data meant.

What they are checking: Working through scientific disagreement with key stakeholders.

How do you keep up with new biologics formulation and process technologies, and is there one you have pushed to bring into a team?

What they are checking: Initiative to drive innovation, not just follow it.

Tell me about a scientist you mentored or a study you led where others depended on your plan.

What they are checking: Leadership and the ability to guide others at a senior level.

What would you do

The CMC team wants a formulation locked in two months, but your stability data will not be complete. How do you handle that conversation?

What they are checking: Making a defensible risk-based recommendation under timeline pressure.

About the work

Walk me through how you would design a formulation screening study for a new monoclonal antibody headed to a high-concentration subcutaneous product.

What they are checking: Depth in biologics formulation design, excipient choice and stability-indicating readouts.

What degradation pathways worry you most for proteins and conjugates, and how do you detect and control each one?

What they are checking: Mechanistic understanding of aggregation, oxidation, deamidation and conjugate-specific risks.

How do you design a process robustness study for fill-finish, and how do you decide which parameters are critical?

What they are checking: Risk-based process characterization and use of DoE.

Genetic medicines like AAV or LNPs behave very differently from proteins in drug product. What would you need to learn first if you moved onto one of those programs?

What they are checking: Awareness of modality-specific challenges and honest framing of their own gaps.

What goes into choosing a product presentation, such as vial versus prefilled syringe, and who do you involve?

What they are checking: Integrated thinking across formulation, combination products and patient use.
