Unfortunately it's easy to make claims on one's resume that are hard to refute. Yes, you worked there, but what did you actually do? What did the code you wrote look like? Every writer who advocates FizzBuzz or something related has specifically mentioned these are candidates with resumes that got them to the interview stage, but who couldn't actually write code. Looking at open source code or a portfolio is an extension of that, since one doesn't really have time in an interview to do anything more complex than FizzBuzz.
