Google won't you apply to work there without giving your college GPA, despite the fact that all the academic research, and also their own internal research, shows that GPA doesn't correlate at all with job performance.
I don't think Google is asking for GPA anymore. Not for experienced hires, anyway. I can imagine they might still ask it for interns and college hires, where it's relevant. But they didn't ask me two years ago (I was seven years out of university at the time).
Using GPA as a screening measure when members of a racial demographic routinely preform more poorly due to socioeconomic factors, it starts to look more like a proxy for race.
