Received one offer from my 2nd choice firm one week ago. I have one more week to accept/decline. I'm interviewing with my 1st choice firm one week from now, and from what I've heard from a VP in the firm, as long as I don't screw up the interview I'll most likely get the offer.
I have one offer and I'm 100% sure the background check will come back clean. Will I have any problems if I give my notice now, and end up getting the 2nd offer after I've already quit my current firm?
