Wells Fargo Capital Finance vs AllianceBernstein Fixed Income

I'm in a bit of a weird place. I recruited for WFCF FAP internship and got it. I find the group is interesting and think a career in debt or CRE would be interesting (Manager has been very open that if I perform and don't enjoy the work I can switch to Corporate or CRE).

However, my long term passion is to go into fixed income asset management. So yesterday I was just notified I got the first round interview for AB. The position is basically my dream job. Problem is, WF offer expires on Monday and AB's earliest superday is Thursday and the recruiter said they could get back with a decision on Friday.

I've been really grateful to WF recruiting and was super pumped when they told me. I've heard great things about the program and coming from a non/semi-target I wasn't expecting anything else to come along. If anyone has any advice that'd be great. Is there any chance WF pulls my offer if I ask for an extension?
