hmm, a lot of good points have been discussed. but, in reference to listing a lot of languages on your resume makes it look like you are padding for inexperience, what about web programmers? a real webprogrammer is going to easily know a good amount of languages/framworks. ex.: xhtml, xml, css, ajax, soap, javascript, jquery, php, mysql, etc. etc. I suppose you could put 'web programming languages' down, but how do they know wtf that means? maybe you are a .net web programmer, or javaEE, or php, etc.
Obviously the languages you know would come out in a conversation about projects you have done, but thats during the interview. I think there might be a few thoughts on this: 1) the resume is padded for inexp. 2) he knows a lot of technologies related to his work, 3) he's a smart ass who programs a lot
anywho, when i see a resume that has a fair number of languages listed i tend to think they are more of a computer nerd, which to me is a good thing. If you've got just Java, C++, or VB on there; I read it and think these are the classes he/she took in college and they don't really know shit. Now, maybe if was a little more in depth, like Java EE, Swing, VB.net+LINQ, or something a little more detailed (aka some frameworks listed) I would think they actually know something about what they are doing. They may not be an expert in the fields listed, but having knowledge of what they are and how the work (in a nutshell) is a lot better (imo) than some chump who wrote a few hello-worlds for his CS minor.
but, then again I've never had to hire anyone, so I suppose I don't really have this kind of exp.
