Your question is Scoping an Ambiguous Data Program. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Tell me about a time you managed a complex data project end-to-end. How did you define the scope when the problem was still ambiguous, align stakeholders with different priorities, and decide what success looked like?
