Your question is Synchronous vs Asynchronous Microservices. 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).
Can you explain the difference between synchronous and asynchronous communication in microservices?
Discuss how each approach works, when you would choose one over the other, and the implications for latency, coupling, reliability, retries, observability, and failure handling. Use a practical request flow or event flow to make the comparison concrete.
