Interview Prompt
Errors and redirects say little about how the service performs, so we only look at successful calls in `api_calls`. Report each endpoint's slowest and fastest latency, the gap between them, and how many times slower its slowest call is than its fastest.
Summary
Latency spread across endpoints.
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
