A while back I was part of a hiring team for a new consultant. (I worked for one of the Big 4 Accounting Firms.) He was presented to us from a search firm and supposedly carefully vetted. After a couple of incidents that rubbed me the wrong way, I pulled up his resume and called the last company he had listed. Asked for HR and confirmed he had never resigned from his previous position. He was working both jobs at the same time. It's not like either position was low level either. I remember my mouth literally dropping open. Shocking how much people try to get away with.
On another note my oldest had an internship with Good Year last year - they called every single employer he has had - beginning with Soergel's Orchards. Vetting is not rocket science, just tedious.
