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 characterization result that changed the development plan.

What they are checking: Impact rather than data generation

The posting asks you to drive innovation and enhance platforms and capabilities. What would you want to improve here?

What they are checking: A specific ambition rather than a willingness to contribute

The posting spans Senior Scientist II and Principal Scientist I. Where do you place yourself, and what would stretch you?

What they are checking: Honest self-placement against a two-level posting

What would you do

How do you work with an external manufacturing partner whose process differs from your development setup?

What they are checking: Control over a process you don't run

How do you decide when a formulation is good enough to move forward versus needing another round?

What they are checking: Judgment about when to stop optimizing

This is based at North Chicago within a global development organization. What travel would this realistically involve, and does that work for you?

What they are checking: The global footprint and its practical demands

About the work

This role leads biologics drug product formulation and process development. Walk me through a formulation you developed and the problem it solved.

What they are checking: Formulation ownership rather than participation

What do you watch for in a biologics formulation that wouldn't matter for a small molecule?

What they are checking: Whether the biologics specialization is real

How do you design a robustness study so it tells you where the process will actually break?

What they are checking: Study design, a named responsibility

You'd support scale-up and technology transfer to internal and external manufacturing sites. What goes wrong most often in a transfer?

What they are checking: Real transfer experience, which many development scientists lack
