“Tell me about a time you failed.”

Why they ask this

Resilience and learning agility are key predictors of success. Interviewers want to see that you can handle setbacks, take ownership, and grow — not that you're perfect.

How to answer

STAR + Lesson. Situation → Task → Action (including where it went wrong) → Result → What you learned.

Sample strong answer

Use STAR. Pick a real failure, own it fully, explain what you learned, and show how you applied that lesson.

Example: 'Early in my career, I was leading a product launch that I was convinced would succeed. I ignored early warning signs — beta users weren't engaging as I expected — because I was too invested in my original thesis. We launched to the full user base and saw a 60% drop-off in the first week.

Owning that failure in front of leadership was one of the hardest conversations of my career. But the lesson changed how I work. I now build in explicit checkpoints to challenge my own assumptions. I ask: what would have to be true for this NOT to work? That discipline has prevented at least two major misfires since.'
