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 complex technical problem you identified and resolved on your own.
What they are checking: Independence on complex systems, which the posting stresses with work done without close supervision.
How do you work with the product owner to close open issues and enhancements before a release?
What they are checking: Whether they collaborate actively to get decisions made rather than just logging tickets.
What would you do
A developer says your bug is not a bug, it's how the system was designed. What do you do?
What they are checking: Ability to resolve disputes using requirements and the product owner, without making it personal.
The release date is fixed, and you won't finish all your test cases. How do you decide what to test?
What they are checking: Risk-based prioritization and clear communication of what remains untested.
About the work
Walk me through how you turn business requirements into automated test cases.
What they are checking: Whether they can read requirements critically and design tests that cover both the happy path and the edges.
Explain how you'd plan regression, integration, performance and user acceptance testing for a new release.
What they are checking: Understanding of each test type's purpose and how they fit together in a release cycle.
What automation frameworks and languages have you used, like Selenium, Playwright, Cypress or REST Assured?
What they are checking: Hands-on automation depth rather than only manual testing experience.
Write out loud a defect report for a bug where a form saves but the data doesn't show up on the next screen.
What they are checking: Whether their bug reports have clear steps, expected and actual results, and enough detail to fix quickly.
How would you set up a performance test for an application, and what results would worry you?
What they are checking: Practical knowledge of load testing tools and what response times and error rates mean.
How do you keep an automated test suite from becoming flaky and slow over time?
What they are checking: Maintenance discipline, since unreliable suites get ignored and stop catching real defects.
