Avoid any examples that would frame you in a poor light. You don't have to have an example where others on your team could not govern their emotions. Focus on your soft people skills instead. Being able to non-defensively communicate with a wide range of personalities is a trait of strong leadership. Investing the time to work with employees who take more effort to get on the same page makes for a much stronger team. This brand of team collaboration enhances work relations. Exemplify your ability to communicate non-defensively.

"Hmm. Well, all the teams I've worked with have been pretty great. We've all been emotionally grounded, so I've known none of them to get angry about anything. There was one example I can give. This was early in my position there. A coworker decided they were going to quit but were too scared to go through with it, so they called me and told me to pass it on to management that they quit. This wasn't very professional. They were having many issues, so it didn't surprise me. So I passed the information on, and we were all disappointed that this employee took this approach, and gave no notice. In the end, we found someone who was a better fit for the role and this improved the performance of our team. I think about that person now and again and hope they figured out some stuff and found work that was a better fit for them."
