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).

That... that's your evidence that Google are a bunch of racists? Because they want to know how well applicants did in college?

Okay, then. Good luck with the lawsuits.

Well, INAL, but maybe that actually might be a good standing for a disparate impact suit. https://en.wikipedia.org/wiki/Disparate_impact

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.
