Interview Prompt

Next week's reliability review covers the high-traffic endpoints, the ones that handled at least 80 calls. For each, surface the total call count, the average latency, and how many calls exceeded the 500ms SLA.

Summary

Every endpoint has a speed and a reliability story.

How This Interview Works

  1. Read the vague prompt (just like a real interview)
  2. Ask clarifying questions to the AI interviewer
  3. Write and run your SQL against a real database
  4. Answer the interviewer's follow-up questions, then get a hire or no-hire decision
