idk it seems illegal to me.. the civil rights act says in very plain language that it's illegal to discriminate based on immutable characteristics during hiring.
Break down a hypothetical scenario:
1. Post a job, anyone can apply.
2. Candidate applies, goes through the hiring process, the team likes them and wants to make an offer.
3. Not a woman or PoC so not allowed to make an offer yet.
So at this point lets say you go out and interview a woman or PoC.
a. If you like the woman or PoC and want to give them the job, then the first person was discriminated against because if they had been a different race or gender they would have got the job.
b. If you don't give them the job then you can check the box saying you interviewed the diverse candidate, but this is at best purely performative because the other outcome was discriminating against the first person.
Logically, it is impossible to have this policy and not be breaking both the spirit and letter law in my opinion.
Also the implication of "diverse managers hire diverse teams" is that the diverse managers will discriminate based on race and gender.
