Just to add to this, I feel like there's a ton of ways to "accidentally" introduce a lot of bias in hiring: referring everyone from your college's club to the company, brain teasers that require some irrelevant cultural background, mandatory in office/remote cultures, off site decisions. Heck I even saw a company that advertised that they go surfing together every weekend for bonding.

I'm not sure what can be done with these cases, and I know people, of various protected out-groups, that have specifically mentioned those as reasons not to join a company.
