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
Walk me through a medical device component or subsystem you designed from a user need all the way to verified design. Where did you have the most say?
What they are checking: Whether they have truly owned design work end to end or mostly supported someone else's decisions.
Tell me about a time you led prototyping and testing and the results told you the design was wrong. What did you do next?
What they are checking: Whether they let data change their mind or defend the design they already liked.
Describe a complex design issue you solved using data. What analysis did you run, and how sure were you before you made the change?
What they are checking: Whether they use structured root cause and statistics, or guess and hope the next build works.
Tell me about a time you mentored a less experienced engineer on design controls. What did they struggle with?
What they are checking: Whether a staff-level hire can raise the team's skill, not just do excellent individual work.
How do you work with quality, regulatory and manufacturing early in concept so the product can actually be built and cleared?
What they are checking: Whether they bring in other disciplines early instead of handing off a finished design and fighting later.
What would you do
How would you set up a Voice of Customer session with clinicians so you learn what they actually do, not just what they say they want?
What they are checking: Whether they know how to observe real clinical workflow and avoid leading questions that confirm their own idea.
You're halfway through verification and marketing asks for a feature change that touches a requirement you already tested. How do you handle it?
What they are checking: Whether they can protect design control and explain the real cost of late changes without simply refusing.
Sage aims for simple interventions with big outcomes. How do you keep a design simple when every function wants to add something?
What they are checking: Whether they can defend simplicity with reasons tied to the user and the clinical outcome.
About the work
How do you turn a vague user need, like a nurse saying a product is hard to open with gloves on, into a design input you can actually verify?
What they are checking: Whether they can write measurable, testable requirements instead of restating complaints in engineering language.
What belongs in a Design History File, and what goes wrong on a project when the DHF is treated as paperwork at the end?
What they are checking: Whether they understand design control as a working discipline that protects patients, not a box to check before launch.
How do you decide which verification tests need a statistical sample size and how do you pick that number?
What they are checking: Whether they can tie sample size to risk and confidence rather than copying whatever the last project used.
