Let's Build a Real QA Interview Bank - For Everyone Who Needs It Right Now

QA Jobs

Dear Community, @trust_level_2

Lately I’ve been seeing a lot of posts from people in our community who are job hunting, being laid off, or trying to break into QA for the first time, whether as a manual tester, automation tester, or SDET.

It’s tough out there. And the generic “top 10 interview questions” articles don’t really cut it when you’re actually preparing for a real interview under real pressure.

So I want to try something different.

If you’ve been through a QA interview recently - as a candidate or as an interviewer - would you share what you actually encountered? Not from the textbook stuff.

It doesn’t have to be perfect. Even just one question and how you answered it could be exactly what someone else needs to hear right now.

To start things off:

  • What’s a question that caught you off guard - and how did you handle it?
  • What answer do you wish you’d given but only thought of after?
  • If you’re a hiring manager, what separates a good answer from a great one?

This thread is for anyone who’s preparing, pivoting, or just trying to get back on their feet. Let’s make it something people can actually use.

Drop whatever you have. Every contribution helps someone. :folded_hands:

One question that caught me off guard was:

“Tell me about a bug that developers initially rejected. What did you do?”

At first, I focused on explaining why I believed the bug was valid. Looking back, I realized the interviewer wasn’t just testing my technical knowledge—they wanted to understand how I collaborate with developers.

The answer I’d give now would be:

In one case, a developer believed the behavior was expected. Instead of arguing, I collected clear evidence by documenting the exact steps to reproduce the issue, attaching screenshots/videos, and comparing the behavior with the acceptance criteria or business requirement. We discussed it together, and after reviewing the evidence, we reached a common understanding. The issue was either fixed or clarified with the product team.

The biggest lesson I learned is that QA isn’t about proving someone wrong. It’s about working with the team to ensure the product behaves as intended.

For anyone preparing for interviews: don’t just memorize testing concepts. Be ready to explain real situations where you investigated issues, communicated with developers, handled disagreements, prioritized bugs, and made decisions. Those conversations often matter more than textbook definitions.

One question that caught me off guard was:

“Tell me about a bug you found that had the biggest impact on the product.”

Initially, I focused on explaining the bug itself. Later, I realized the interviewer was more interested in my thought process than the technical details.

If I were answering it today, I’d structure my response like this:

  • How I discovered the issue.

  • Why it was important (impact on users or business).

  • How I reproduced it consistently.

  • How I collaborated with developers to investigate it.

  • What changed after it was fixed.

I’ve learned that interviewers often want to understand how you think as a QA engineer rather than hear a list of bugs you’ve found. Demonstrating your investigation process, communication, and ability to assess impact usually leaves a stronger impression than simply describing the defect.

That realization has changed the way I prepare for QA interviews.
