Interview Prompt

The on-call team is auditing our node fleet for machines that have dropped out of active service. Among the nodes marked draining or offline, count how many machines are affected.

Summary

Some hosts wear many hats. Count the machines, not the mentions.

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
