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).
How would you handle offline synchronization for a financial transaction feature?
Explain how the mobile client queues transactions without connectivity, securely persists and transmits them later, prevents duplicate submission, and reconciles conflicts with the server. Discuss where machine learning could assist, such as prioritizing reconciliation or flagging anomalous offline activity, without allowing a model to determine financial truth. Cover failure handling, observability, security, and testing.
