Pros
Infosys is one of the best outsourcing companies to work for. There is lot of scope for learning and growth. You learning curve is very steep for the first 2-3 years.
Cons
It is an outsourcing company. It is not a good company to work for more than 2-3 years if you are interested in improving "technically". After 2-3 years you become a "lead" and most of the work is in excel or word or support. Because of the peer pressure ever one wants to become a project manager (microsoft project) or a project co-ordinator - not an Engineering manager as in software companies. Being a consulting organization, every one has to be a pseudo "sales" person. There is no work-life balance if you are onsite as the calls are always night after 8-9 hours at work. You work with "freshers" only. Not that freshers are a problem, but the basic problem is always the same- resource issues.
