2.2Quality Philosophy Questions

"What does quality mean to you?"

This is the most important question in any QA interview. Your answer reveals your entire testing philosophy.

Weak answer: "Quality means the software works correctly and has no bugs."

Strong answer: "Quality means the software reliably delivers the value users expect, across all the conditions they will encounter. Zero bugs is not the goal -- the goal is that the bugs that remain do not matter to the user. I think about quality across multiple dimensions: functional correctness, performance, accessibility, security, and usability. My role as a QA engineer is to make quality visible and measurable so the team can make informed trade-offs. Sometimes shipping faster with known limitations is the right call. Sometimes blocking a release is the right call. Quality engineering is about providing the information that makes those decisions good ones."

"How do you decide what to test and what to skip?"

Strong answer: "I use risk-based prioritization. I assess each feature across two axes -- likelihood of failure and impact of failure. High likelihood and high impact gets full coverage. Low likelihood and low impact might get no dedicated testing beyond automated smoke tests. I document what I am skipping and why, so the decision is explicit rather than accidental. Chapter 22 of this guide covers the risk matrix approach in detail -- I apply that framework in every sprint."

"How do you define 'done' for testing?"

Strong answer: "Testing is done when the remaining risk is acceptable to the stakeholders who own that decision. In practice, that means: acceptance criteria are verified, edge cases identified during three amigos are covered, regression suite is green, exploratory testing has been performed on the highest-risk areas, and any open issues are documented with severity and business impact so the product owner can make an informed release decision. Done does not mean perfect. It means informed."
