Phase 15 · Interview Preparation

Incident & Reliability

Troubleshooting Scenarios

Part of the DevOps Roadmap.

Summary

'The site is down, walk me through what you'd do' — testing a calm, systematic diagnostic process rather than a specific memorized answer.

How to Learn This

  • 1Practice a repeatable structure: check monitoring, check recent changes, check logs, isolate the layer.
  • 2Prepare a real troubleshooting story from your own practice work, even a small one.
  • 3Practice narrating your reasoning out loud — the process is what's being evaluated.
