Your question is System Design: Current Product Architecture. 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 your current product's architecture: how components communicate and how threads are managed in a pool.
Asked in the Round 2 stage. Be prepared to describe service boundaries, communication patterns, request lifecycles, thread-pool sizing, queueing, backpressure, and failure handling. Explain how your design supports ML inference or other latency-sensitive work, and clarify assumptions rather than inventing product details.
