No, a few months of coding classes do not make someone a developer. However, it does separate them from other people by demonstrating that they are hard-working, curious and have an interest in the field. In my mind those types of people are the ideal candidates for junior-level positions. Much more so than some CS graduate who went through the motions to earn a degree on theoretical computer science and thinks he's now a software engineer. (I mean, last time I checked, the vast majority of computer science degrees were not terribly relevant to professional software development.)
