Interview Prompt
Raw call counts in `api_calls` make some endpoints look widely used when a few chatty users drive most of the traffic. For the platform team's deprecation review, surface the endpoints called by more than 60 different users, with the headcount for each.
Summary
Shared credentials 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
