Hello there. Hope you are doing good. I would like to tell you that the salary depends on the colleges more and less on the specialization that you have opted for. There is a possibility that a certain college has more number of marketing companies visiting the campus instead of finance or vice versa but it is hard to say which among them has a higher pay scale. You should aim for the colleges whose placements are good for a particular specialization.

I hope you found this answer helpful. Good luck for your future.
