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 time you found a serious bug late in a release. What did you do and who did you tell?

What they are checking: Whether they raise bad news early and clearly, even when it puts a ship date at risk.

Tell me about a time you automated something manual testers were doing by hand. How did you get them on board?

What they are checking: Whether they can change how a team works without making people feel replaced or ignored.

What would you do

Our products run on factory floors that feed people and make medicine. How does that change the way you think about what to test first?

What they are checking: Whether they rank test effort by real-world risk instead of by what is easiest to automate.

A developer tells you the bug you filed is not a bug, it is how the feature was designed. How do you handle that?

What they are checking: Whether they can push back with evidence and requirements without turning it into a personal argument.

About the work

Walk me through a test automation framework you built or maintained. What made it hold up as the product changed?

What they are checking: Whether they design automation that survives product change, or write scripts that break every release.

You have a test that passes on your machine and fails about one time in five in the pipeline. How do you track it down?

What they are checking: How they separate a flaky test from a real timing bug, which is common with hardware and network-connected software.

How do you decide what belongs in a unit test, an integration test and an end-to-end test?

What they are checking: Whether they understand the cost and speed tradeoffs of each layer instead of pushing everything into slow UI tests.

How would you test software that talks to a physical device, like a controller or drive, when you cannot always have the hardware on your desk?

What they are checking: Whether they know simulation, mocking and hardware-in-the-loop approaches for testing industrial products.

What languages and tools have you used to write automated tests, and which one would you pick for a new project here and why?

What they are checking: Whether their tool choices come from reasons they can explain, not just habit.

How do you keep an automated test suite fast enough that developers actually wait for it?

What they are checking: Whether they treat suite speed and reliability as part of the job, since slow suites get ignored.
