Very much tracks with my experience.<p>At a previous job, I built a sophisticated anonymization system for our candidates. While I think it helped somewhat, it wasn't nearly as efficient as just looking for candidates in different places.<p>We also lost some brilliant candidates because, in my opinion, the lead engineers would change their criteria if they didn't personally identify with the candidate. They didn't think they were doing it, but they were.<p>If I had to do it over again I would probably not bother with the anonymization and focus on all problems at the top of the funnel.<p>Companies with a large proportion of people from allegedly elite universities have a much more difficult problem to solve. Their culture is always going to interpret openness to candidates from different backgrounds as a danger, and try to rebuild those walls.
