I'm presently working in TCS, only been a year and I'm still a trainee.
I passed my B.Tech in 2011.
I don't want to continue anymore, the higher up HR guys behave with us like we are peasants.
I want to do an MBA, maybe come back to the IT world and work in some management position.

So can anyone guide me as to which major should I go for in MBA?
Salary isn't an issue, I want more onsite opportunities.
I have missed the CAT 2012 deadline for application, so name some exams and colleges left for which I can apply now.

I sound like a total noob in this matter
