This is the intended effect of the tech interviews that HN hates so much. Interviewers talk to the candidate and write down feedback about how the interview went. Then a hiring committee reads the notes and makes a decision. The hiring committee never sees the candidate, so can't judge their appearance. When I was doing interviews at Google, we were also trying very hard to write feedback like "the candidate said XXX" instead of "she said XXX", so that that source of bias was not available to the hiring committee. (It's not perfect, of course, because the person writing the feedback can be biased by those things. But it's better than looking at resumes with photos attached.)
