What they want to know is if you can accept advice positively and help others improve respectfully, showing you work well in a team. You should say you listen carefully to feedback to improve your work and share helpful suggestions with teammates while making sure everyone understands each other clearly.

Example: I welcome feedback because it helps me improve and grow, especially when learning a trade like pipefitting. When I offer feedback, I focus on being clear and respectful, making sure it’s helpful rather than just critical. For example, on a team project, I once suggested a small change in approach to a colleague, which made the task smoother and built trust between us. Communication like this keeps everyone moving forward together.
