The last time I changed jobs within the company I was already employed by, I had to submit official sealed transcripts from every school I went to since 1973. Only elementary school was not required. Even my flight school transcripts. After I got the promotion the HR manager told me how many people at the company he had to fire over false credentials. They even monitor your Linked in profile for false claimed experience, skills, tenure, padding.
My mother got her first job as a secretary after the last of us kids were old enough for grade school. She lied about her skills, experience, and education. She taught herself typing and shorthand in two weeks before starting. Thirty years later she was on the board of directors for that same company.
They even monitor your Linked in profile Yet another reason not to have a presence on Linked In, Facebook, Twitter, Gab, Truth Social, etc ...
