Example: “In my previous role as a network engineer, I worked with a customer who was very demanding. He would often call me at all hours of the day or night to ask for updates on projects that were already completed. This made it hard to focus on other work because he would constantly interrupt me. Eventually, I scheduled a meeting with him to discuss his behavior. After talking with him about his expectations, we came up with a plan to manage his requests more effectively.”

When answering, it can be helpful to mention a specific example of when you gave constructive criticism to a peer or colleague and the positive outcome that resulted from this conversation.

This caused them to miss important meetings with clients and sometimes even skip out on their scheduled breaks. After talking with them about the importance of punctuality in our job, they still continued to arrive late to work. So, I decided to have a one-on-one meeting with them to discuss the issue further. They apologized for their behavior and promised to arrive to work on time every day moving forward.”
