Clearly the main issue of the post is the answer to the interview question. Although I think it's a very good answer and that to me it would probably mean I would be hiring a guy which is humble, which always views his knowledge has something that still could be better and has a view of his own code has something imperfect, and so he tries very hard to always know more and improve, and that would mean in the end he is just one of the best choices to hire, I think that in most companies that guy would never be hired.

Although it sucks, nobody gives any value to humility anymore. They want the confident, "I'm an expert" kind of guy, so giving as answer that the worst code you've seen lately is your own, without any kind of explanation of why you think that (that you view your knowledge has something which as always a long way to go) would probably be a instant KO to the poor humble interviewee.
