Q:

Customer service representatives usually work with a team. How do you see yourself working with a team, and what role would be playing?

Our response to this shouldn’t be a negative one. Instead, affirm the interviewers that we can work with a team or even individually. It does not matter if we are team member or a team leader, as long as we tell them what we can do then it surely helps.
