Interview Prompt
On the platform team's latency board, endpoints look faster than they are because every user's earliest call in `api_calls` lands quickly. Leaving those opening calls out, report each endpoint's average latency over the remaining calls.
Summary
The first call is a promise. Judge the ones that follow.
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
