Welcome to your interview.
The question is on your right: Assess Product Market Fit. 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 are working on a product that has started to show early traction, and the team is debating whether it is ready for a bigger growth push. Leadership wants a clear read on whether the product has real product market fit or just early noise.
How would you evaluate whether a product has achieved product market fit before scaling spend?
