Failed IB Recruitment, Offer from Corporate Treasury Thoughts

Hey everyone, I've been lurking on this sight for a while and thought I'd come here to hear other perspectives on my current situation.

I'm currently a junior at a target that was going through IB recruiting, but unfortunately did not win any offers. I am currently sitting on a Corporate Treasury summer analyst position at a top BB (JPM/MS/GS), and wanted to hear anyone's thoughts on the role. Is this the type of role that will give me good experiences to set me up for an MBA? Have other people in corporate treasury been able to move over into more FO roles within the bank? 

Obviously, I'm a little bummed out that IB recruiting didn't work out for me, but I feel optimistic about the offer that I currently have and wanted to hear what the full range of corporate treasury looks like.
