Interview Prompt

Given an api_calls table with user_id, endpoint, status, and call_time, find users who retried the same endpoint within 5 minutes of a failed call (status != 200). Return each user, endpoint, and the count of retried calls.

  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
