Your question is Owning Offline Sync Under Ambiguity. 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 had to own an offline data persistence and backend synchronization problem in a mobile app when requirements were unclear or stakeholders disagreed on the trade-offs. How did you decide what to build first, align people around the approach, and what was the outcome?
