Quick definitions (what companies usually mean)
- QA: quality ownership — test planning, exploratory testing, basic automation.
- SDET: automation-first — frameworks, CI integration, flaky test fixes, tooling.
- SET: engineering productivity — test architecture, infra, reliability for testing systems.
How to choose (simple rule)
- If you enjoy coding + frameworks → SDET
- If you enjoy product + edge cases → QA
- If you enjoy platform/infrastructure → SET
Skills checklist (India interviews)
- 1 automation tool (Playwright/Selenium) + one language
- API testing (Postman + basic scripting)
- Test design: boundary/negative cases
- CI basics + reporting
- Debugging flaky tests + logs
Project ideas that map to real JDs
- Mini E2E framework + HTML report + retries + screenshots
- API contract tests + CI pipeline
- Flaky test simulator + stabilisation notes
