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 design for high-concurrency bidding in a live auction system?
Clarify the auction semantics, consistency guarantees, latency target, traffic profile, and whether machine learning is required on the critical bidding path. Explain the online architecture, data flow, capacity assumptions, evaluation, and failure handling.
