I don't know the answer to your question exactly. I got to the second interview with BoA for a PT teller. I forgot to list that I ran a home based business on my background check and I think that kept me from being hired. Last time, last year, my creadit score for 780 and I've never been fired or have any criminal background. I don't know for sure if i didn't get the position, but it's been over a week and I haven't heard back, so I's asmusing I did not.
So as for your question, then yes I think your background might be enough to keep from being hired.
