What are the tell-tale signs in an interview that a developer is not competent?
<p>I'm specifically talking about interviewing for a position for a very experienced and competent C++/C#/Java systems developer, not a html, javascript web developer position.  In my experience nervousness is often not a good indicator, because many good developers get very nervous under pressure, so what is a good indicator?</p>

<p>Hmmm... sorry, <a href="http://stackoverflow.com/questions/400646/how-to-weed-out-the-bad-programmers-from-the-competent-ones-in-the-interview-proc">this</a> didn't pop up when I went to ask this question.  I've been told previously I'm not necessarily meant to delete it, but just post a link to the existing one.  Please, if people think I should delete it, post a comment here to let me know, quite happy to, it seems <em>very</em> similar to the other one.</p>

<p>... or should I just close it?</p>
