Chat representatives provide online customer service through a live chat support system. Your specific job duties vary, depending on your company and industry. But general responsibilities may include using online chat portals to answer questions, resolve payment issues, or help customers place orders. Technical chat representatives may help customers fix or solve problems they have with their electronics or service systems. Most chat representatives focus on communicating through text chat systems and email, but companies may also ask you to use a voice chat system. Chat representatives may work in a customer support facility, an office, or remotely from home.
