As the topic asks, I'm wondering how experimentalists (specifically in Physics) market themselves to potential employers. I can see some theory/computational people listing programming skills on their resume if they've worked with simulations or modeling, but I want to know what experimentalists would try to do. I ask this because I am doing an REU right now (at a company, not a univ.) and I have the option of switching projects from a fairly hands-on optics one to a project where I'll be able to learn UNIX and IDL (neither of which I know very well yet). I realize this REU won't decide my entire career path, but I'm curious about how would I talk about experimental skills on a resume.
