There is much more to customer service than simply answering telephone calls, and your interviewer will want to ensure that you understand all of the goals you must meet along the way. Some of these include your average call handling time, your issue resolution rates, your transfer rates and the number of calls you escalate. “I will work hard to exceed the goals presented to me by the company. I always give 110% in everything I do, and I am not afraid to ask for advice if I feel that I am struggling with any goal” would be a great answer.
