Your question is Improving a Broken Test Process. 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 found that your team's testing lifecycle was weak or inconsistently followed, and you took ownership to improve it. Walk me through what was broken, how you influenced others to change the process, and what results you achieved.
