Huh? I have never known someone whose employer demanded to see a transcript. Not saying it doesn't happen, just that I don't believe it is as common as you seem to imply. Graduate schools want transcripts, yes, but they are generally more concerned with GRE scores than GPAs.
Google asked for a transcript when I interviewed (late 2008, about 3 years out of school). I told them I could get them one, but it would take 2 weeks and my other offer was getting antsy. That was the last I heard of it. My offer letter arrived about a week later.
Very often, things that are hard & fast requirements aren't actually. According to the media, Google was in a hiring freeze when I was hired and wasn't hiring anyone. According to the blogosphere, they only hire people with 3.7+ GPAs, yet I had a 3.0.
