TCS IJPs

I have recently received an offer from the BFSI unit for a Java developer role. I have got to know from somewhere that the project is of maintenance type and not an actual production level project. (By reading the linkedin profile of one of the panelist :P)

If anyone is aware of this BFSI unit (Morgan Stanley acct in Bangalore), can you please throw some light on the kind of projects and learning which I can expect?

1. Is there any commitment period for an account like for 2 years or so, we have to stay in it and cannot apply internally for another account?
2. Do IJPs in TCS actually help you get a salary hike and a better project to work on, as a lateral entry.
3. After how much time can a new employee start applying for internal IJPs?

Thanks in advance!
