I've walked people out of the office over things like this. Generally, people like this will shotgun every language and technology about which they've ever read a blog entry. It usually gets them past the phone screen (which I try to spread out on my team so everyone learns to do them) and in the door. When I see them claiming experience with any of the "cool" technologies, I usually throw them a couple questions related to Haskell[1], ocaml, Erlang, Lisp, 6502 assembly, etc. If they flub that area without acknowledging that it was a toy project, I'll know they are probably lying someone else. I'll be a lot more aggressive zoning in on the design and implementation of their most recent project. If they're soft, where I might normally give a little room for "nervous at interviews," they're pretty much done. However, if they nail it, I know we're going to be able to work well together. Especially so if they get excited that someone is asking them about something...that...they'll...never...get...to...work...with...in...our...boring...IT...department. sigh [1] This one is almost too easy.
