About your past
Tell me about a CAPA where the first corrective action did not work. What did you learn?
What they are checking: Whether they verify effectiveness and dig deeper rather than closing actions on paper.
How do you run an internal audit so people see it as useful rather than as a hunt for blame?
What they are checking: Whether they can build a quality culture where findings get fixed instead of hidden.
Tell me about a quality improvement project you started yourself. Why that problem, and what changed?

How do you supervise inspectors and technicians who sometimes have to give bad news to production?
What they are checking: Whether they back their team and help them communicate findings without creating conflict on the floor.
What would you do
A customer or third-party auditor is coming in three weeks. How do you get the plant ready?
What they are checking: Whether they can prepare a plant for external audits through real readiness, not last-minute cleanup.
You find that several SOPs no longer match what operators actually do. How do you decide whether to change the SOP or change the practice?
What they are checking: Whether they understand the posting's focus on current SOPs and can judge which version is right.
A supplier keeps sending parts that are just inside spec but cause trouble in assembly. How do you handle it?
What they are checking: Whether they can manage vendor compliance with data and work with suppliers instead of only rejecting lots.
Production wants to ship a lot that failed a measurement by a small margin because the customer is waiting. What do you do?
What they are checking: Whether they hold the line on quality while finding a proper path like deviation approval with the customer.
About the work
Walk me through how you run a CAPA from the moment a nonconformance is found to closing it out.
What they are checking: Whether they know the full corrective action process, including root cause and checking that the fix actually worked.
What root cause tools do you use most, and give me an example where one of them changed what you thought the cause was.
What they are checking: Whether they use tools like five whys or fishbone thoughtfully rather than as a formality.
How do you know a measurement system is good enough to trust before using it to accept or reject product?
What they are checking: Whether they understand gauge capability and calibration, which underpin customer certifications and testing.
