I just granted permission for United Healthcare to perform a check on my background. I suspect this might be a clue to a potential job offer. What happens next? And what sort of time frame should I expect? Any ideas?

There is a online assessment, over the phone interview and lastly face-to-face interview. I was offered a back up position. If someone decided not to take the offer at the last minute I was the back up but unfortunately for me everyone took the offer. It was a bad experience I felt devastated.
