Tell me about a recent stressful situation and how you handled it.

A great way to show you can maintain your composure during stressful times is to include an example. If you didn't handle stressful events well when you first became a manager explain how you have grown since then.

"When I first became a manager, I used to take a dissatisfied customer's comments personally and struggled to make the situation right. I realized that I needed to improve and asked one of the senior managers, that handled these situations with ease, for feedback. It was as if a lightbulb went off when he told me not to take a customer's feedback personally. Reminding myself that customer is sharing feedback keeps me calm when making the best decision."
