Only list the technologies you're fluent in on your resume

Only list the technologies you're fluent in on your resume, or make it clear what your skill level is if you're listing things you've had exposure to in the past. I use to add qualifiers to my resume; like beginner, intermediate, and advanced when I listed a tool, language, or technology. Now I don't list very many technologies at all, since most managers I've interviewed with have been less concerned with technology and more concerned with skill. I think that's natural as you get more experience under your belt. But I could be wrong.

When you're pulling together your resume, only list tools and technologies that you actually know. Don't list the stuff you've had "exposure" to. If I can't ask you an interview question on it (like, write code in language X, or tell me how you would configure Y, etc...) then you either don't want to list it, or make it very clear that you've only had exposure to it. When looking at resumes nothing turns me off faster than seeing a laundry list of tools and technologies without context for how they have been applied by the candidate.

For me, it comes down to trust. In an interview, I'm trying to figure out what you can really do. If you get my hopes up by listing Java, Ruby, or some other techno-widgit I'm really looking for, and you can't actually do it, I don't know what else you can't really do that you're telling me you can. Even if you're really good at all the other stuff, once I feel like you've falsely represented your skills, it's hard to dig out. On the other hand, if someone has all the right skills but is missing the techno-widgit, I'm likely to hire them. I can teach someone Ruby.

For me, loosing the interviewer's trust isn't worth the eye-candy of listing all the technologies.
