This narrative is pushed constantly, to the point where it's started to lose believability with me. It's used by large companies to justify their BS hiring practices when the reality is a bad hire won't hurt the company that much. It's used by small companies to justify nonsensical interview practices.
> Human questions. Does this question give the candidate a chance to display a wide enough range of himself, socially, that you are comfortable that he can work well with other people?
I try not to display much of myself socially when I'm at work. I'm there to work. I'll gladly go out for lunch and be friendly with coworkers, but it's not hanging out with friends. It never will be.
