About your past

Tell me about a time production was waiting on your test equipment. How did you handle the pressure?

Tell me about a time you had to work with design engineers who didn't think about testability until late.

What they are checking: Whether they can influence design early to make products easier to test well in production.

What would you do

What they are checking: Whether they can troubleshoot environment, setup and handling differences between sites methodically.

Your test shows a marginal failure rate creeping up over a few weeks. What do you do?

What they are checking: Whether they treat a trend as a signal to investigate the product or the tester before it becomes a real escape.

About the work

Walk me through a test fixture or test station you designed, from requirements through release.

What they are checking: Whether they have owned the whole cycle of test hardware, software, debug and documentation for production use.

How do you decide what to test on an AED or ventilator at end of line versus what's covered by design verification?

What does test method validation mean to you for a medical device, and how have you done it?

What they are checking: Whether they know how to show a test reliably catches bad units, including repeatability and gauge studies.

Which languages and test frameworks have you used to write automated test software?

What they are checking: Whether their software skills match the test automation the role needs to build and maintain.

How do you document a test station so a technician at a supplier site can run and maintain it without you?

What they are checking: Whether they write clear procedures and controlled documentation that let the equipment work without its designer.

How do you control changes to test software once a station is released for production?

What they are checking: Whether they respect change control and revalidation, which keeps a regulated test process trustworthy.
