Handling a Production Incident
Prompt
Walk me through a production incident you handled. How did you diagnose, fix, and prevent it?
How this round runs
I will pick one story and drill into it — your specific role in the response, how you found out, and what mechanism you put in so it can't recur. A war story you watched from the sidelines won't survive the follow-ups.
Model answer
Pick a real incident you were genuinely part of, with a timeline you can recall. Lead with one sentence on impact (what broke, who it hit), then walk the arc — detect, mitigate, root-cause, prevent — anchored on what you did at each step.
A strong answer is first-person about your role ("I took incident commander…", "I made the call to fail over…"), separates the fast mitigation from the real fix, is specific about the root cause rather than the symptom, and ends with the concrete mechanism — alert, guardrail, test — that means it can't recur silently.
- A real incident with a timeline, and clarity on YOUR specific role
- Separated immediate mitigation from the permanent root-cause fix
- Named the actual root cause, not just the symptom you restarted
- Added a concrete mechanism so it can't recur silently
- What was your specific role in the response?
- How did you find out — alert, or a user told you?
- What was the root cause, versus the symptom you first saw?
- What mechanism did you put in so this exact thing can't recur?
