> A while back, I did rough envelope calculations that if one of the major FAANG companies hit their diversity goal, there would be none left for any of the rest of them.

Not to mention, if the other companies also wish to hit their diversity goals, they will be forced to take on weaker hires, since the (already small) pool of adequate hires has been exhausted. In my opinion, diversity hiring is an anti-pattern. Hiring should instead ignore demographics information rather than use it to try and achieve some optimal representational balance. If demographics information are completely ignored in the hiring process (which is impossible if you do on-site hiring), then no one can accuse you of favoring a particular group of people.
