Pros
It depends which team are you in, really. The supprting departments in Infosys are probably the best in the business: VISA, Travel, Settlement etc. If your manager / team is good, you will be a very happy person in Infosys. If you dont gel with your manager, it will not be a smooth ride. I have believed that the managers here are very opinionated towards people.
Cons
Not the best place to work if you want great salary. Its better than most but certainly not the best. Feedback system is a disappointment, the way Infosys looks towards its employees has changed drastically over the years. Now all the 'focus' towards the employees is to make them more competent, which is to say 'more sellable'. The company does not give a damm to your work life balance, it is upto you to figure that out.
