When you have a surplus of people who can do the job, then you can afford to filter based on luck. In this case, limiting interviews to people like you who you will end up being social with, instead of people who can just do the work. The problem, of course, is that the odds are good he's hiring people who are less skilled than some people he's filtered out. In a perfect market his product would get beaten by whoever hired those better candidates he ignored, but we live in an incredibly imperfect market and it probably won't make a difference.
