In most cases, working as a customer service representative will also mean opening customer accounts or placing orders on a computer. Most companies for which you will work have their own proprietary software, so you will receive on-the-job training for this. However, you should be familiar with the basics of computers so that you can successfully manipulate the various programs, enter data, notate the customer’s account with the actions taken on the call and much more. “I have worked with computers for many years and I am very familiar with them. I can assure you that I will learn any software quickly and effectively” is a solid answer for this question.
