Interview Prompt
List every recovered retry in `api_calls`: a later call from the same user to the same endpoint, made within 5 minutes of a server-side failure. The on-call engineer wants each pair as the `user_id`, the `endpoint`, the failed call's time and the retry's time.
Summary
Detect retried API calls within 5 minutes of failure.
How This Interview Works
- Read the vague prompt (just like a real interview)
- Ask clarifying questions to the AI interviewer
- Write and run your SQL against a real database
- Answer the interviewer's follow-up questions, then get a hire or no-hire decision
