It's worth considering how the question is phrased. A "conflict at work" could indicate a conflict between yourself and another employee, or a time you exhibited strong leadership skills to resolve a dispute between two other members of the team. It could also mean you had a personal conflict of interest. In your answer, exhibit integrity. Detail the situation leading up to the conflict. Include the steps you took to de-escalate. Explain how it was resolved. Do your best to exhibit your soft skills and your adeptness at non-defensive communication.

"A member of our team was going through some heavy personal issues. Their behavior was erratic at times. I had a couple of talks with them, hoping to mentor them or just to lend an ear. My approach ultimately failed, as they weren't interested in help. I gave them time to collect themselves and later addressed the situation by explaining how their performance was under evaluation and how the department's perception of them on the team had changed. I also apologized for overstepping my bounds, detailing my motivation, and explained that I wouldn't again cross those boundaries now that they've set them. Soon we got along as if nothing had happened between us. Sure, I was trying to help, but in the end, there's only so much one can do."
