My counter argument to this is that the later in the process your face is shown, the fewer people have the option to discriminate and therefore the fewer arbitrary filters you have to pass through. And ideally the people who are discriminating at that point are the people you'd actually be working with, so their discrimination (however arbitrary) is more relevant bc you might continue to experience it on the job (not to say that jobs where a person is discriminatory isn't one worth taking or possible to work past.)
