Welcome to your interview.
The question is on your right: Measure Core Feature Engagement. 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.

What metrics would you watch to understand whether engagement in a core feature is improving?
