I actually thought that line was a joke when I first read it. "We don't hire non-citizens, Hispanic people, or anyone over 30" sounds a lot worse than "we evaluate candidates according to an algorithm trained to predict work performance."
Before tech I did a stint in recruiting. We had a client demand only "white sounding" names. We ignored that and provided any qualified candidate. They complained because they mistook the recruiters name for an applicant. We fired that client the same week. It was a truly disgusting thing to be asked and I'm glad my company made the right call. Any future client that asked that was immediate grounds for client dismissal, i.e. didn't require management approval.
I'm conflicted about this, on the one hand it's completely wrong, but on the other hand would a non-white person even want to work for them? In the end their own biases will cause them to fail.
There are plenty of people who need to work to eat and can't be picky with employers.
