I believe it’s compulsory or at minimum a way to protect themselves. I always choose the “rather not answer” option to every question that specifies it. The hiring managers rarely get to see the answers.

Oddly enough, I’m a white male and the most protected class “abuses” I’ve ever witnessed is when I’ve been told I wasn’t allowed to hire white males. I’ve actually been told I could not hire any one except a women before. My team was shorthanded for a year. I work in a niche that is probably 90%+ male and probably 70% white.

What’s also weird is, I usually hire through recruiters so when I tell them “only send me female resumes” the search just goes radio silent and I don’t even see what kind of talent I’m missing out on.
