It’s actually not hard to sniff out assholes. You just ask them about how they resolved a recent conflict and picture yourself on the other side of the story. We had a great net eng candidate who zero of the interview team said they’d want to work with. Otherwise smart and capable, we gave him s hard pass.
As one grows and evolves, one learns to better themselves. A fairly significant number of smart and capable people have been guilty of acting in not so ideal manner when dealing with incompetent or otherwise incompatible people but the answer to questions like "give me an example of an encounter or interaction that did not go as well as it could" is not to sugarcoat or misrepresent, I think part of growing up is to own one's mistakes honestly, recognize them as such and learn from them and if an interviewer believes they can really ferret out liars that are in reality asshole but have ready answers for such question in order to take a hard pass on folks that disclose past mistakes honestly, well, I am not sure I consider it to be the best strategy, but I am still learning things.
