You might think customer service is a job of a lone wolf - it's not. If you have already worked as a customer service representative, you must know how important teamwork is - the answer should be YES. Share your team stories and explain how you could accomplish specific jobs with the help of your team. By doing so, you can clearly show the interviewer how well you do with teams. As you know, customer service is sometimes about escalation. Hence, the interviewer needs to know that you possess the ideology of passing the issue on to someone who can deal with it. Also, before appearing for the interview, research them and make a note of what's important to them. With the help of this question, they can assess if you can work independently or need supervision all the time. This is a frequently asked interview question for call centers that offer services in customer support.
