As a new associate, you will be working with one or more partners. You will not be working much on generating your own business, but rather you will be on a team of lawyers working on the client's case. Being on a team like this may mean that you are doing a lot of work that may not be recognized or acknowledged by the client. Being a team player means providing support and sharing in the victory (or loss). This is also an opportunity to show that you are comfortable contributing your own opinion to someone who presumably has more knowledge and experience than you. The firm likely wants an associate who is comfortable sharing their view of the situation rather than simply going along with whatever the partner says.
