Need your help: Wipro BPO

Friends, I need your help.

I want to know about Wipro BPO at Kolkata, its work environment, salary scale, job timings, night shift timings, fluency in english, future scope and every little detail that can be useful. Is it ok to leave a good job (with less salary) for this kind of job. I am totally confused. Also is there anyone here who is working there. Please share your valuable experience.

Please help.

Thanks in advance.

Subrata Bera.
