Interview Prompt
On-call keeps finding that the single slowest endpoint for each HTTP method in `api_calls` is a one-off outlier. The API platform team wants each method's runner-up instead: the method, the endpoint and its latency at the second-highest latency logged for that method.
Summary
Almost the slowest. By method.
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
