Interview Prompt

Given an api_calls table with user_id, endpoint, timestamp, and status code, write a query to find retries after failures. A retry is when the same user calls the same endpoint within 5 minutes after a call with status >= 400. Return user_id, endpoint, the failed call time, and the retry time.

How This Interview Works

  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
