According to who? I’d be willing to bet a lot of money that the departments that hired them did not come out and say “we hired these applicants because they are female/black!” That seems to be the conclusion that your home department came to, solely on the basis of face appearances. And quite frankly, it does a disservice to the minority and female candidates coming out of their department - I’d be angry if my department assumed I only got my job because of my gender or race rather than my own skills, potential, and experience.
