I give this as advice because I don't really care if the candidate likes me or not. What I care about if he can control himself and behave befitting the occasion.
If you can't do that on an interview there is no way you can do that later during normal work.
And I have clear, strict no asshole policy. We come to work to solve problems which does not require insulting each other. There is going to be problems and there is not going to be any insults because we understand we all want the same thing even if we have different capabilities, approaches and value systems.
I understand this doesn't mean people don't want to insult each other. There are always going to be tensions and what not. But I want workplace to be safe space for everybody. There is already enough stress, no need for people to be additionally miserable by asshole coworkers who can't control themselves.
