Welcome to your interview.
The question is on your right: Measuring Success for Internal Tools. 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.
How do you define and measure success for an internal platform or data tool at Pmg when traditional user metrics like daily active users may not apply?
