Interview Prompt

The quarterly capacity review is tomorrow and the VP wants a utilization heatmap by region and node type. Show average CPU and memory utilization for each combination so the team can spot over- and under-provisioned segments.

Summary

CPU and memory, region by region.

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
