Your question is Owning a Flaky Selenium Suite. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Tell me about a time you inherited or built a Selenium-based web test suite that was unreliable or hard to maintain. How did you diagnose the problem, improve the stability of the automation, and what measurable impact did your changes have on the team or release quality?
