Not necessarily. When we talk about someone being a good culture fit at the place I work, we look for someone who's respectful, approachable, not condescending, and who wants to empower their coworkers.
There are many brilliant technical people who are jerks—we don't want to work with them. (And not to say that there's not a place for super-smart people who are assholes, but we try not to hire them.)
Sure, evaluating that someone is respectful, tactful and approachable is best done with a few hour interview. Riiight.
Anyone who believes that should be immediately fired. Those things come out in a few months at earliest, as does lack of professionalism or competence. Even a good judge of character needs a sample in non-contrived circumstances, which a hiring interview is not.
I'd actually like to see hard research data on this... What I have is soft data on how people are in general horrible judges of character. In that plain old days mining is often more accurate.
