Interview Prompt

The platform team ran a developer satisfaction survey but forgot to collect region data. User IDs from the survey match infra node operators, and nodes link to pods which carry region info. They need the average CPU usage (as a satisfaction proxy) per region. Show each region and its average.

How This Interview Works

  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
