Interview Prompt

List each namespace's featherweight from `k8s_pods`, the name of the one pod using the least memory, alongside that memory, so we can rightsize our multi-tenant Kubernetes cluster.

Summary

In every namespace, one pod does most of the eating.

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
