Information request for career

I am in a dilemma and in need of assistance. I have an exploding offer that is set to explode tomorrow. The offer is for back/middle office finance/controlling. I have ultimate careers goals of being in banking. What are the prospects of going from the finance position to banking in a few years down the road?

I also have a few interviews set up with companies where the work will be more like a banker, in regards to transferable skills, but obviously no positions are guaranteed from said interviews. Also, if I accept the offer, set to expire tomorrow, I am no longer allowed to participate in on-campus recruiting, which is where these interviews are set up.

What are the opinions of the members here as to what would be the best for my future? Accept a position in one of the stronger banks, who just acquired a part of a bankrupt bank (hint), or drop the offer and hope for the best in a position with better transferable skills? Etc. Etc.
