It's interesting, my experience at a FANG (which invests heavily in recruiting women engineers) is that approximately 25% of teams are 60/40 men/women, and 75% of them are 100% men. The women I've worked with have told me that this is not a coincidence, that they very quickly learn which managers they will not work under or which coworkers they will not be on a team with, and that they take the presence of other women on the team as an indicator that none of these characters are present. I wonder if the same principal operates geographically - certain regions find that they just never encounter women or minorities in the workforce, and it may have as much to do with the region as the people.
