Darchei Noam-
Let’s say you send in a resume indicating that you went to University of BLAH BLAH. There are no openings so you don’t get an interview.
Then you actually get a degree from a legitimate place and update your resume indicating that. Now you submit a new resume for a position you are qualified for. They toss it in the garbage because they see that you lied in the past.
BTW- Yes I did submit more than one version but the contents were always true.
