I had a little ego for sure. I think under the circumstances that is not too much. Anyone who puts in really a lot of work to improve their knowledge has a little ego. Calling that "a bit much ego" in this context is harsh. I am indeed someone that doesn't like being treated like shit.
Sorry man, hats off to you if you are that humble. For myself, I don't want to be that guy though. I don't consider myself being a person with an oversized ego. But I did not appreciate someone deliberately refusing to hear anything about your past experiences because that would throw his baseline out as the entire choosing of candidates was on the basis on scoring on their tests. And I was not someone that was fresh out of school.
