Resumes are dangerous

Often, when I’m reading a resume I’m thinking: “This guy is great, look at all this experience. He clearly knows Ruby and JavaScript like the back of his hand, and this interview is just going to be a formality”. Then, come the interview, the guy can barely code, much less know the ins and outs of variable scope. It turns out there is very little correlation between how good a resume is, and how the interview actually pans out.
