Pros
good internal material for learning and training yourself.
Cons
I got hired onsite because their visa applications were getting rejected left and right after they abused the system. Many projects were being lost (.i.e, positions were being filled by local staffing firms). They were in a bad spot and accepted my salary demands and agreed that I need not relocate to different locations. But now with them starting this new Global Compensation Model (GCM), I am being ready to leave incase my salary is reduced. They recently started the new Global Compensation Model (GCM) for existing and new employees globally. If you join the company, it is possible that when your project changes, your role and salary will change. For eg, if you join the company with a position of technology lead with a salary of 80,000, they could be assigned to a project a week later which requires only a senior programmer so then your "role" changes to Technology Analyst (though offficially you are a technology lead) and salary changes to that of Technology Analysts (say $75,000). They are doing this because they noticed that most of the client requirements are for developer fill-in positions (In short, Infosys plays the role of a staffing firm in most of the cases) and they have lower margins with technology leads taking developer roles. They make it sound good by saying that if you perform the role of a PM, then you get the role and salary of a PM. But seriously, that's just a carrot to get people to accept this change unlike the iRace change which created a lot of bad sentiment and immidiate negative reaction across the company and media. Besides, there are plenty of PMs and Technology Leads around. So if anyone is joining the company, be aware that the salary you may change if you change your project. Another thing is that they expect you to work more than a normal work day. For eg, they expect you to do additional work at home for other projects or offshore teams...that's because they want to get the maximum productivity and bang for the buck out of each person hired onsite. They already do this with people brought from India because they have less demanding power. They don't understand personal life outside work. They've tried many times to get me to work late night with offshore teams who are not part of my project and all but I refused because I know that if I want, I can easily get a job else where. After they got a taste of my push back, they haven't bothered me much.
