Job offer Morgan Stanley NYC

I was offered a job for a very basic data entry position that is only a few months contract. I was wondering what is the likely hood they hire contract workers once its completed and the likely hood to move to different departments within MS? Also, what are average hours for most departments? This would be for the MS in FIDI. I have another offer at a company that isn't financial, but it's full-time so I'm in a bit of a dilemma. Basically is it a solid foot in the door to take this contract? I've been in the financial sector for 4 years mostly working with data.
