Walk me through a project you're proud of.
Short answer
Short answer: Pick a project where your contribution had measurable impact, walk through it in STAR format, and end with what you'd do differently next time. Pride is fine — modest pride backed by data is better.
Detail
Picking the right project: not necessarily the biggest or most senior — pick one where your contribution is unambiguous and the impact is concrete.
STAR walkthrough — sample answer:
Situation: A previous team I was on had a regression problem with our checkout flow. We were releasing weekly, and roughly 1 in 4 releases shipped with a payment-related regression that customers caught before our test suite did.
Task: I'd been at the company about 8 months and was the QA owner for the checkout area. I felt strongly that we couldn't keep operating this way, but the team was sceptical of investing in more E2E tests because the existing suite was flaky and slow.
Action: I spent two weeks profiling the existing E2E suite — found that 60% of failures came from 8 flaky tests, and the rest from genuinely brittle waits. I deleted the worst flakes (with engineer-manager sign-off), rewrote the wait strategy to use Playwright's built-in auto-waiting, and added 4 focused tests covering the regression patterns we'd actually shipped. I also added a 90-second smoke test to PR CI that ran the three highest-value paths only.
Result: Over the following quarter, payment-related regressions dropped from 1-in-4 releases to 0 in 11 releases. Pipeline runtime improved from 22 minutes to 8 minutes. The smoke check caught two regressions before merge that would have shipped under the old suite. I shared the approach with two other QA peers; they applied a similar pattern to their own areas.
What I learned: I'd assumed the suite needed more tests and discovered it needed better tests. A focused test that always passes when the code's fine and always fails when it isn't is worth 20 broad-but-flaky ones.
Why this answer works: it's specific (numbers, timeframe), it shows you doing real work (deleting + rewriting, not just adding), it has measurable impact, and it ends with a thoughtful lesson rather than triumphalism.
The framing of pride: be proud of the work, not yourself. "I'm proud of how this changed the team's release cadence" lands better than "I'm proud that I single-handedly fixed it."
