The problem with non-coding interview's is its very dependent on the interviewer to determine their capacity, and _many_ people are bad at that. I think if you are good at it, its pretty easy to tell (like < 5 minutes) if someone can do the job. But I've seen very poor candidates get past this screen many times, even when screened by people I otherwise trust. So I know its not a common skill.
