Fortune 50 FP&A Summer Offer or Take a chance on IB?

Hey everyone,

I am currently a Junior/third year and was recently offered a FP&A summer internship at a F50 company and I have a few more weeks to accept the offer but last Thursday though I had a chance to network with a VP from RBC Capital Markets in their M&A Energy IB Division in Houston. I got the chance to express my interest in banking, tell him more about myself, and he really liked me. During my chat with him he gave me his business card and yesterday I called for an informal interview/"conversation" to share with him a little more and my background/knowledge as well as getting to know him and his background as well. In the end he stated that he would give a reference for me through HR for the M&A group in Houston.

My main dilemma here is whether or not I should I go and accept the offer I have now with the F50 company or should I place all the bets on this opportunity? I obviously understand that this chance doesn't really mean too much because in the end its possible I won't get my foot through the door at all even though he referred me. A sub problem here is that I am really interested and would prefer a gig in Restructuring (although I wouldn't mind M&A at all), but unfortunately they aren't recruiting for that (as well as the other banks that recruit here [Semi-Target]). My F50 offer needs a response by Nov. 25 right before Thanksgiving (I already asked for an extension as well so I ran out on buying time options) and I would hear back from the bank about the progress early December.

With this I was ultimately wondering should I take the F50 offer and run and not take any risks and then opt for FT IBD recruiting next fall for Restructuring groups or should I take a chance on RBC? Last thing I want to happen is not getting any gig at all this summer because Spring recruiting here is almost non-existent!

For those of you that suggest I wait for FT recruiting how significant would you say the difference is between SA and FT recruiting and will the F50 position (if I take that route for this summer) add any value to my experience going in for FT recruiting (I have had previous part time/internships at a local hedge fund and served as a financial analyst intern at a local company BTW)

I would greatly appreciate feedback, suggestions, comments!
