I know a FEMALE who blatantly lied about her college and she has NEVER been scrutinized by MAJOR companies. Either they ignore or are incompetent. A resume check takes very little time. I believe many get and keep jobs via winks and nods.
I’ve run into a few frauds that somehow got away with lying about their professional and educational history.
It seems that just about any job I applied for, big or small, practically wanted bone marrow from me and my signature in blood.
