Well after reading a few articles about the bad effects of call centers and the work pressure I would like to suggest those friends that hard work is not your cup of Tea. Please find a job in some govt. sector with less work.
I have been working in this industry since 4 years. I started as a caller and I had the same work pressure but the result is that now I am the Chief Operations Manager of an International Call Center. Its a good field to learn, earn & grow.
