Welcome to your interview.
The question is on your right: Product Case Study Metrics. 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.
Walk me through a product case study you solved recently. How did you define success metrics, and how did you measure performance post-launch?
