Your question is Synchronous vs Asynchronous Processing. 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 the difference between synchronous and asynchronous processing in a high-volume system.
Discuss how each model handles request execution, waiting, concurrency, throughput, ordering, failures, and backpressure. Include a concrete example using a network operation and explain when asynchronous processing is not automatically the better choice.
Scope: server-side application code, networking, and runtime behavior. Do not design a complete distributed system.
