I've worked with previous my boss's son. This guy felt like he was the best at everything and would get annoyed if people gave him critical feedback on anything he did and would insist he was right. Therefore, even when more experienced people told him things he disagreed with, he wouldn't accept their opinion and keep doing it his way.
This caused a lot of people to not want to work with him and, in the end, was a major part of why I ended up quitting.
People like that are impossible to work with. It's a flavour of narcissism where the person in question is never wrong, cannot be wrong, so any mistakes are obviously someone else's fault.
