>I think even Google has discovered that, even in their incredibly quantitative process
Google's process is not that incredibly quantitative. When I interviewed there everyone I spoke to had seen my resume, for example, if you wanted your process to be quantitative you would want your datapoints to be correlated as little as possible.
I think they are doing it more to keep up with appearances (it should look hard, to attract the best candidates and repel the worst ones) than anything scientific. They also copied a lot of their hiring process from Microsoft (and most software houses in SV are just copying from Google).
