Sample Answer
On a web platform serving about 500k monthly users, I ran into a checkout bug that only surfaced in production-like conditions. Roughly 1 in 200 orders would silently fail after payment, with no clear pattern. QA couldn’t reproduce it on demand, and logs looked clean. I started by pulling 2 weeks of payment logs into a spreadsheet and tagged them by browser, country, ISP, and payment type. A pattern emerged: failures clustered around mobile Safari using 4G networks, and sessions were slightly longer than average. I set up a throttled network profile, used browser dev tools to simulate 4G, and added extra client/server logging around the payment callback. That exposed a race condition where a delayed callback collided with our session-timeout logic. I documented exact environment settings, packet captures, and a 6-step repro path with screenshots. Pairing with the backend dev, we added a grace window around the timeout and extra telemetry. We verified the fix with a 3-day canary: failure rate dropped from ~0.5% to effectively zero.
