Your question is Metric That Drove Change. 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 created a metric that drove change.
Asked in the phone screen stage. The interviewer is probing whether you can identify an important but poorly measured problem, define a useful metric, and use it to influence decisions or behavior. A strong response should explain why the metric mattered, how you validated it, who acted on it, and what changed as a result.
