Theres also the whole theory about what languages you know indicates what kind of person you are. Even if you are looking for a Java programmer, the guy who took the time to learn languages that weren't required in their class indicates they have drive to learn on their own. Not a fan of that indicator. I actually know quite a few mega-polyglots. They learn every langugage they can find. But I also know people who know a couple of languages pretty well, but spend their time learning other things. In my spare I rarely want to learn a new language. I'm much more interested in, how did this app solve problem XYZ. I spend a lot of time digging through code that solves problems. In some cases I have to learn a language to learn a solution, but I rarely just grab a book on esoteric language Z, but I know people who do. If you ran the NY Times would you hire people based on how many languages they spoke? It might be interesting, if that's their thing, but in general its no more useful than asking someone to rate themselves on how many operating systems they know well, how many different kinds of mice they've used, or how many text editors they're familiar with.
