I had to ponder on what it is that really sets this sort of person apart, and I think it's the sort of sneering disdain at the idea that any of the other languages in the world are worth anything, or have any good ideas. Or maybe it's the way that when you ask them what's good or bad about some other language, you get back just a list of differences those languages have with Java, and it is simply assumed that all differences are ways in which they are inferior to Java.

And let me say again that it's not specifically Java. I've seen a couple of people that way with C, for instance, though not in an interview situation.
