Tell me about a production issue.

Practice this question
Discussion template: use your own project facts, ownership, and measured outcomes. Bracketed text is a placeholder.

Short explanation:

A production-incident answer explains impact, investigation, mitigation and prevention in a clear order. It should show that you worked from evidence and reduced risk while users were affected. Use a genuine incident and avoid claiming a root cause you never confirmed.

Key points:

  • “Users faced [symptom]. I checked [logs/metrics] and found [cause].”

  • “We reduced impact with [action], then I fixed [change].”

  • “We checked [result] and added [prevention].”

  • Mention how you verified recovery and what changed to make recurrence less likely.

Interview point:

  • Being calm and specific about uncertainty is stronger than pretending the cause was obvious immediately.
