I would do whatever is necessary to get to the UPS interview. The long term stability of the bank position is questionable at best. How old are you? Assuming you've got 20 years until retirement, odds are that corporate gig will disappear well before UPS ever does (though nothing in life is guaranteed).

One thing you have to bear in mind is that UPS has a competitive pool, so even if you interview successfully in two weeks you could end up "swimming" for a year or more.

I'm guessing if you take the corporate job, you'll be in training and won't be available to interview at UPS? Obviosuly only you know the specifics of your life, but think of that UPS interview as a potential winning lottery ticket. Not too many people get the opportunity to win the lottery and you've already got 6 of 8 winning numbers

Good luck!
