> How does a policy like that look in practice?

I used to work for a manager who would blatantly say "I will not hire a white person for this position". Of course, it wasn't an official policy to exclude people based on race. I'm pretty sure that would be illegal? But in practice, some hiring managers would sometimes reject or not even consider candidates of certain races. I've also seen people on hiring panels lower standards explicitly because of "diversity" (but to be fair, only when the candidate was on the fence of hire/no-hire).
