Why interviewers ask this
Nearly every workplace has personality mismatches, and the interviewer wants to know whether you can keep collaborating productively despite one, rather than letting the friction spill into the quality of shared work. This question also tests self-awareness, since strong answers usually include some reflection on how your own style contributed to the friction, not just the other person's. It is a soft skill question that carries real weight because interpersonal breakdowns are a common reason teams underperform.
How to structure a strong answer
Describe the nature of the mismatch specifically, whether it was a difference in communication style, work pace, or approach to problem-solving, rather than a vague personality clash. Explain the concrete step you took to keep working relationship functional, such as agreeing on explicit ground rules, adjusting how you communicated with that person specifically, or focusing conversations strictly on shared deliverables. Close with the outcome for the actual work, since that is what interviewers ultimately care about more than whether you became friends.
Example answer
I worked closely with a colleague on the finance team whose communication style was very blunt in written messages, which I initially read as dismissive of ideas I brought to our joint reports. After a couple of tense exchanges over email, I asked to switch our coordination to a weekly 15-minute call instead, since tone is easier to read out loud than in short messages. That change alone resolved most of the friction, and I also learned that his directness came from wanting to move fast, not from any dismissal of my input, so I adjusted by bringing more concise, decision-ready proposals to our calls instead of open-ended questions. We ended up delivering three quarterly close reports together without further issues, and he specifically asked to keep working with me on the next project cycle.
Common mistakes to avoid
Do not use this question to describe someone as simply a bad or difficult person without acknowledging any role you played in the dynamic. Avoid a story where the resolution was that you stopped interacting with the person or had them moved off the project, since that shows avoidance rather than a working solution. Also keep the focus on professional collaboration rather than trying to describe becoming genuine friends, the interviewer cares about functional teamwork, not friendship.
