Welcome to your interview.
The question is on your right: Clarify Direction Before Building. 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 working on a product initiative where the engineering path is fairly obvious, but there is still debate about what user problem to solve and what outcome matters most. The team could start building quickly, but the product direction is not settled.
How do you approach a project where the technical solution is clear, but the product direction is still uncertain?
