Welcome to your interview.
The question is on your right: Prove Product Success With KPIs. Take a moment with it first.
Talk your thinking through with me if you like - when you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes). Discussion and graded submissions share your five interviewer interactions, so spend them well.
You've launched a product solution and need a clear way to show whether it is actually working. The team wants a metric set that captures immediate user response, longer-term business impact, and a simple way to communicate progress over time.
How do you track KPIs and metrics to prove that the solution is working?
