The idea that someone has no social skills because he doesn't ace in a highly contrived situation which has no correlation to the way he will communicate in his job later is pretty weird (Do you hire engineers/developers or high-stake, high-pressure negotiators, e.g. diplomats?). As is the idea that you should optimize your hiring process for what people do "most of the time". You want to optimize for what is MOST IMPORTANT about their job. If I need someone who goes to customers I wouldn't select for people that can drive Formula 1 cars efficient, even if it happens to be the case that they are driving most of their work time.
