its just one side of the story. i dunno wat call centres at kolkata are upto but delhi is a better.who r attending calls at cal centres?...........IIT grads or SRCC chaps. mostly those who dont have a strong acad background.
call centre shd just b taken as time pass. to work for 6 months and make a bank balance around 7-8k and keeping ur big aim in life like competetive exam like cat.its nothing much, just selling ur voice for money.so if they pay u handsomely that u can suffice it can b considered.
life is very tough. atleast there is some respite with callcenter booming up.
