Collaborative design review (manager-led)

Problem Collaboratively design a system or application with the interviewer in a "design review" format — a discussion, not a whiteboard grilling. Pick a realistic service relevant to the role, then drive the conversation: clarify requirements, propose an architecture, and reason about trade-offs (data model, consistency, failure modes) as a peer responding to the manager's prompts.

Areas to go deep

• Requirement clarification and scoping the problem down.
• Data model and consistency choices.
• Failure modes, bottlenecks, and the trade-offs behind each decision.
