Interview Prompt

A reliability review is hunting for duplicated API responses: cases where two different calls returned the same HTTP method and the same status code. List those matching pairs by their two call IDs, highest status codes first, and keep only the top 20.

Summary

Same status, same pattern. Coincidence?

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
