If you can't do better than "shitty personality," I guarantee I wouldn't hire you. On the other hand, "Unwilling to respect colleagues they wouldn't personally be friends with" is a valid reason to make a no-hire decision.
"Can you tell me about a time you didn't get along with a colleague and how you worked through that situation?" One of my go-to questions and often illuminating. A good answer I have heard somewhat often ends with, "Stupid Jerk was never my friend, but we figured out how to work together and produce value anyway."
