Interview Prompt

We're auditing infrastructure capacity across our fleet. A node is overloaded when either its CPU or its memory is running too hot. Surface each unique overloaded node's hostname, region, and node type.

Summary

CPU above 90. Memory above 80. Red alert.

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
