Pros
I am an American hired under a 'global talent' initiative to help diversify the company. For the most part the employees I've interacted with - almost exclusively Indians - are very competent, intelligent and hard-working. When you are not on a project you are on 'bench' - we were told at any point in time 20%-25% of the delivery staff is on bench, waiting to deploy to new projects. You are probably supposed to be doing some kind of work when on bench, but I've never known anyone to do it, or seen repercussions for not doing it.
Cons
Infosys is an Indian company, run by Indians who make Indian assumptions (like that you won't have a problem being called at 11:30pm) and all policies are geared toward Indian nationals, even if there are deputed to the U.S. HR at Infosys is TERRIBLE, though it's not entirely their fault - in a recent meeting we were told by an HR rep that there are about 20 HR employees in the U.S. covering over 12,000 employees here. This explains why, whenever I contact HR with a question, I usually have to bug them several times and when I do hear the answer is either incomplete or simply a restatement of the policy that I am asking about - no attempt to clarify.
