Remember that a job in a call center is just that...a job. By any stretch of imagination, never confuse it with a career. Mammon, conversing with foreigners, the classy interiors, the hip employees, the cafetaria, the workplace is all very inviting prima facia and the precise reasons that would lure you to work there. But it is these very perquisites that end up as reasons for wanting to throw in the towel and leave. the cafetaria is a far cry from healthy food and burgers and pizzas could never replace dal-chaawal. once their accent and their grievances wear off on you, your foreign customers end up being just a pain at the wrong end.
i used to train for call centers in soft skills, telephone etiquette, accent, etc at a consultancy for call centers in Pune. I left within 2 months. There is no future career prospects in it. How many actually end up climbing the corporate ladder to become team leaders? What are your skill sets after you leave, besides conversing and pitching in an accent? Where do you stand with your already settled peers?
