You've broken the site guidelines badly here. Would you please review them and stick to the spirit of this site when posting to HN? Note this in particular:

In this case what is the stronger interpretation? He cites and example of "bias in interviewing" but does not point to any biased action of the interviewers, but rather the fact that they are of a different race, which makes him uncomfortable. The obvious interpretation, that an interview conducted by people of a certain race is inherently biased against him. Calling this "bias in interviewing" also carries the connotation that this is the company's fault and their responsibility to fix. In this case, that they should exclude people from the interview team based on race to reduce interviewee anxiety. If the poster I replied to had only mentioned that he got anxiety around white interviewers without the accusation that this constitutes bias against him I would not have responded that way.
