If you started programming when you were 12 and you've been programming for fun more than 4 hours a day every day since then, you are going to be drastically better than someone who starts programming in their first year of college and only does it to graduate. It feels like a bimodal distribution because you then get both kinds of programmers interviewing for jobs at the same age when they graduate from college and one of them is going to feel drastically different than the other.
