Interview Prompt

The cluster reliability team is triaging the pods in the k8s_pods table that keep crash-looping instead of starting cleanly. Find each namespace's average memory used across those pods, heaviest footprint first.

Summary

CPU versus memory. Resource efficiency.

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
