Uber Qa Engineer Mock Interview

Tell us about a time you found a serious defect late in the release cycle—what was your investigation process, how did you communicate risk and next steps, and what changed in your testing approach afterward?

Uber relies on fast, reliable experiences across mobile, web, and services—walk us through how you would design a test strategy for a new “estimated arrival time” feature that depends on real-time signals, including how you’d handle flaky tests and data variability.

A passenger reports that the app shows the wrong pickup location only for certain driver pickup modes and specific device GPS behaviors—how would you reproduce it, narrow down root cause, and validate a fix without breaking other location-based flows?

Describe a situation where you had to balance thorough QA coverage with tight timelines (e.g., during a promotion, peak demand, or an urgent incident). What tradeoffs did you make, and how did you ensure quality remained measurable?

We use automation heavily, but you also need judgment about what to automate—what’s your approach to building and maintaining a regression suite for critical Uber APIs and UI flows, and how would you decide between contract tests, end-to-end tests, and unit/integration tests?
