Your question is Async Microservices Communication. 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).
How would you design an asynchronous communication pattern between two microservices?
Explain the architecture and the tradeoffs involved. Cover message transport, delivery guarantees, retries, idempotency, ordering, schema evolution, failure handling, observability, and how you would validate the design at production scale.
