Interview Prompt
Each account holds several API tokens in `api_tokens`, and every token records its scope and how many requests it served. We want the scopes that show up somewhere on our tokens but on none of the tokens of the account with the highest total request volume.
Summary
One account carries the traffic. Trace it back to everything it can touch.
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
