Interview Prompt

A server shows up in `server_logs` once for every line it writes, but we only care about the last time each one spoke. List every server with its most recent log timestamp so we can spot the ones that have gone quiet.

Summary

Each server's last heartbeat.

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
