Talk about failure and feedback

“Tell me about a time you failed” and “Tell me about critical feedback you received” test self-awareness and growth. Everyone makes mistakes; interviewers want to see that you own them, fix what you can, and change how you work.

• A real failure: something that went wrong because of your decision or action, with consequences. Not a disguised strength (“I work too hard”).
• Ownership: “I underestimated the migration’s risk” - no blaming others or circumstances.
• Response: what you did to limit the damage at the time.
• Learning and change: the specific habit or process you adopted, ideally with evidence that it worked later.

For feedback questions, the same arc applies: the feedback, your honest reaction, what you changed, and how you know it helped.

Example: “I shipped a schema change without a rollback plan and caused a 40-minute outage. I led the incident response and wrote the postmortem. Since then I write rollback steps into every migration plan, and our team adopted it as a checklist item - we have had no migration outages since.” The last sentence proves the learning stuck.
