Interview Prompt

We're auditing which API tokens are still carrying live traffic. Surface the 5 busiest tokens that haven't expired, and show each token with its issuance date.

Summary

The busiest keys are the ones that never had a deadline.

  1. Read the vague prompt (just like a real interview)
  2. Ask clarifying questions to the AI interviewer
  3. Write your sql solution with real code execution
  4. Get instant feedback and a hire/no-hire decision
