Pros
Service based company and NOT a software engineering company You dont have any pressure to learn anything as you are working in Glorified Call centre You can enjoy your life like hell ,You have a good respect in Indian society who thinks that you are working in a software engineering company(Because Indian society does not know reality) You can learn the art of buttering ,politics ,social skills
Cons
Except learning anything useful ,you will learn How to waste time of 9–10 hours completely everyday.Lot of employees in this company commute also, Which also takes 2 hours everyday because of the heavy traffic, so one can literally waste 13 hours everyday without doing anything. You wont learn anything about Software or Computer science or any thing related to career growth ,as you will be doing data entry ONLY in Some tools ,You are working in a GLORIFIED call centre.
