Interview Prompt

Our API monitoring tracks latency per endpoint. For each endpoint, surface the gap between the highest and lowest observed latency, the ratio of highest to lowest, and both extreme values. Exclude any entries with zero latency, and rank by the ratio from highest to lowest.

  1. Read the vague prompt (just like a real interview)
  2. Ask clarifying questions to the AI interviewer
  3. Write your sql solution with real code execution
  4. Get instant feedback and a hire/no-hire decision
