- In practice, a production system using HTML develops a user-visible reliability, latency, cost, or correctness problem. A strong candidate would clarify the constraint, choose a reversible response, communicate the decision, and verify the result using p95 latency, error rate, throughput, saturation, cost per request, recovery time, and user impact.

Interview explanation
Say it clearly in the interview
Start with the problem, explain the main execution or data flow, and close with when HTML is a poor fit. I would explain the failure mode, tradeoff, and how I would test the result.
