Accepting Wells Fargo IBD vs. Waiting for BAML Superday

For context: This is for a Summer Investment Banking Analyst position.

Hey guys,

I'm a bit of a predicament. I have an offer for Wells FargoIBD SA, but the issue is the offer expires this week and I've asked them to push the deadline but they said they aren't willing to budge on the date. I have a BAMLIBDsuperday next week, after the Wells deadline passes.

I'm looking for advice. Should I accept the Wells Fargo offer, thereby losing the chance to work at a better firm? Or should I reject Wells and pray that I get the BAML offer? Also, what are the consequences if I accept the position at Wells and renege if I get BAML?

Thanks for your help guys - I really appreciate it.
