Interview Prompt

We only have budget to add hardware in three regions this quarter, and a region's load is the total CPU percentage across all of its nodes in `infra_nodes`. Which three regions should get it?

Summary

Five regions with the hottest CPUs.

How This Interview Works

  1. Read the vague prompt (just like a real interview)
  2. Ask clarifying questions to the AI interviewer
  3. Write and run your SQL against a real database
  4. Answer the interviewer's follow-up questions, then get a hire or no-hire decision
