Welcome to your interview.
The question is on your right: Define Launch Success Criteria. 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're preparing to launch a new product capability and want to align the team on what success looks like before the launch plan is finalized. Different functions may care about different outcomes, so you want clear criteria that can guide decisions and avoid debates after release.
How would you define success criteria for a launch?
