Call centers provide telephone and internet-based customer service and support. The first major call center in India was established by GE in 1998 to take advantage of lower costs and the large English-speaking population. Call centers have evolved from primarily voice-based customer support to also offering email response, web chat, and e-CRM services both for domestic and international clients. Call centers attract youth by offering well-paid jobs requiring minimum qualifications along with benefits like free transportation and subsidized meals. Good English communication skills are the main requirement.
