Tell me about a time you disagreed with a teammate.

How to answer this behavioral interview question: a complete STAR example, the mistakes interviewers watch for, and the follow-ups you should expect.

A strong STAR example answer

On a checkout redesign project, a senior engineer and I disagreed about scope. I wanted to ship an incremental improvement in four weeks; he advocated for a full rewrite that would take three months. The tension was real — standups got terse, and the team could feel it.

As the feature owner, I needed a decision the whole team could commit to. Instead of escalating, I asked him to walk me through his technical concerns in a one-on-one. His core worry was that the legacy payment code would make even small changes risky. That was a legitimate point I had underestimated.

I proposed a middle path: we would ship the incremental UI improvement, but he would get two weeks to build a thin abstraction layer over the payment module first. I took that plan to our manager with data on the revenue risk of slipping a full quarter, and she approved it.

The compromise shipped on a five-week timeline. Conversion rose 8 percent, and the abstraction layer later cut integration bugs roughly in half. More importantly, my teammate told me later he felt heard, and we worked well together on the next two projects. He is still the person I call first when a decision feels one-sided.

How to structure your own answer

• Situation: Set up the project and the nature of the disagreement.
• Task: Clarify your role and what was at stake.
• Action: Explain how you made your case and sought a resolution.
• Result: Share the outcome and what you learned about collaboration.

Common mistakes to avoid

• Painting the teammate as the villain — interviewers want maturity, not victory stories.
• Choosing a trivial disagreement (like code style) that reveals nothing about your judgment.
• Leaving out how you actually resolved it — the "action" step is the whole point.
• Claiming you were simply right, with no concession or learning.

Follow-up questions to prepare for

Interviewers use follow-ups to verify your story is real. If you use this question in a real interview, expect probes like:

• What would you do differently if the same disagreement happened today?
• Has a teammate ever changed your mind completely? Tell me about it.
• How do you handle disagreements with someone more senior than you?
