Your question is Optimizing High-TPS API Endpoints. 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 how you would optimize an API endpoint that handles thousands of requests per second?
Discuss how you would clarify requirements, identify bottlenecks, estimate capacity, and improve throughput and latency. Cover caching, database access, concurrency, load balancing, graceful degradation, monitoring, and how you would validate the changes in production.
