Failure

Tell me about a time you failed to convince someone.

Why interviewers ask this

Interviewers ask this to see whether you can lose an argument and still take something useful from it. They want a story where you were probably right, the other person stayed unconvinced, and you can name what you would do differently. Stories where you secretly won are not what they are looking for.

STAR tip

Pick a real failed influence moment, not one where you eventually got your way. Show what you tried, where it broke down, and what part of your approach you have changed since.

Sample answers

Engineer

I tried for two months to convince our team to migrate our background jobs to a different queue system. The current system was unreliable and costing us about four hours a week of debugging. I wrote a proposal, ran a benchmark, and presented it twice. Both times the team agreed in principle and did not commit. The lead engineer said the migration risk was higher than the upside. He was probably right at that headcount. I did not move him. Six months later we had a major incident on the old system and the team migrated within a month. I had been right on the diagnosis but wrong on the timing and the framing. What I do differently now is, I do not try to convince anyone of an infrastructure migration before there is concrete pain in the room. Proposals before pain are almost always premature, no matter how clean the benchmark.

Product Manager

I tried to convince our CEO to delay a launch by three weeks because our customer support team was not staffed to handle the volume. I wrote a memo, ran the numbers on expected ticket volume, and met with him twice. He launched on the original date. Support melted in week two and we lost about forty customers to slow response times. I had been right. He told me later that he had heard me but had judged the launch window mattered more. The thing I did wrong was that I had argued the support side without bringing the head of customer support into the conversation. He needed to hear the concern from the person who would own the failure, not from me. I now make sure the person closest to the cost is the one who delivers the warning, not the person closest to the data.

Common mistakes

  • Picking a story where you eventually won and calling it a failure
  • Blaming the other person for not listening
  • No specific lesson you actually changed
  • Vague description of what you tried and why it did not work
  • Pretending you never push for things that get rejected
