When an interviewer asks about your favorite part of working on a team, they are looking to gain insight into your collaborative skills and how you function in a group setting. It also gives them a sense of what motivates you and what you find fulfilling in a work environment, as you will be working on multidisciplinary teams as a nurse. It's important to be honest and specific in your answer, highlighting specific examples of successful teamwork and how it contributed to your personal and professional growth. Ultimately, the interviewer wants to know if you are a team player and if you will be able to work effectively with others in their organization.
