You can assess almost nothing that would distinguish one qualified candidate from another to determine who is better spending five minutes with a person. The fact that you see the faults you predicted when you were overruled on hiring decisions is a confirmation bias, not a scientific study of any kind.

Job interviews are a terrible method of hiring good long term people, just a necessary evil to weed out the moronic or insane. The concentration has to be long term on how the person does on the job, the willingness to work hard to retain good people and get rid of ones who aren't working out.

People who are involuntarily committed are observed for more than an hour, because it's known that an insane person can hold it together and appear normal for longer than that period of time before they start talking to people who aren't there.

I couldn't be more sick of posts with "that one interview question" and people who think they are clairvoyant "five minute judges" of character.
