help - exploding BB offer

sugaricing

situation:
got a sales & trading full time offer from a lower-tier BB (bank A) that explodes by the end of this month. the graduate program is non-rotational and starts at an earlier date (which I prefer). i am offered the asset class i refer too.

bank B: completed all interviews currently waiting to hear back. really liked the bank and its culture. 18-months rotional program, don't know which asset class i will end up with. i think i performed quite well during the assessment center. one of the interviewers (MD) even told me he thought i am a really good fit for the role and if i just be myself for the rest of the day i should have no problem at all. problem is, the bank is in the process of finalizing headcount and can't speed up the hiring process. results will be out in the 3rd week of Jan earliest.

bank C: a bigger BB. probably pays a bit higher than A & B too. 2 year rotional program, asset class undetermined. liked the culture liked the people (pretty much same situation as B). think i  performed relatively well during final rounds but had no indication from interviewers. HR said they still have another round of AC in early Jan and decision won't be made until then!

so what can i do here? seems like bank B and C won't be able to expedite the process at all.. should I just sign with bank A? but then if I do get offer from B & C in the future... they are bigger and better names....

advice please!!!

merry x'mas!
