Your question is Post-Meeting Anonymous Survey System. 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).
Explain how you would design a post-meeting anonymous survey system.
Clarify the product and privacy requirements before proposing an end-to-end design. Address survey delivery, anonymous response collection, aggregation, optional ML-based question selection or feedback analysis, online versus batch processing, evaluation, and operational failure modes. State the assumptions you need about users, meetings, response volume, latency, retention, and compliance rather than assuming unstated business facts.
