That’s not necessarily the case. (1) They can still sort rank by quality of institution within the subgroup. (2) I also suspect that outside of top 10 CS programs, that universities sort ranked by proportion of women tend to have higher quality candidates than average. (3) If you build a repudiation for attracting female talent then you may be more likely to attract some of the top women in a given pool—women who might normally go to FANG. Personally, I think the last reason provides an arbitrage opportunity that let’s small companies that focus on women compete for talent in a way that FANG can not.
