I don't doubt he's harsh, but berating employees privately is very different from swearing at an interviewer about past wrongs done to you. One makes you a harsh boss; the other makes you seem a little unstable. I don't have anything against swearing, personally. I also don't have anything against drinking wine in a bathrobe with your hair all messed up. But if somebody who wants to be the CEO of a major corporation showed up showed up at a restaurant for an interview in a bathrobe with messy hair chugging Prosecco straight from the bottle, I would find that questionable as well.
