Interview Prompt
Error alerts during last night's incident keep pointing at a handful of API routes, so the on-call engineer wants every endpoint in `api_calls` that failed more than 5 times. Show each one's failure count alongside its average latency.
Summary
The routes generating the most noise.
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
