25 QA Engineer Interview Questions & Testing Answers

QA Engineer Interview Questions: Manual, Automation, and SDET

QA engineering interviews test: test strategy design, automation framework experience (Selenium, Cypress, Playwright), API testing, performance testing, and quality metrics. SDET roles additionally test coding ability at a level comparable to software engineers.

The critical QA interview question: "How would you design a test strategy for this feature?" Your answer must cover unit, integration, and e2e testing, plus edge cases, performance, security, and accessibility — demonstrating breadth beyond just functional testing.
