Surprising thing is that most recruiters don't want to check if a candidate is actually qualified. We sell live coding tests (www.TestDome.com) and often get the response that testing limits recruiter's "pool" of candidates. Basically, they send everybody with a nice looking resume directly to an interview. Once a recruiter told me: "We tried testing before, but 2 out of 3 candidates failed the test before we could send them to a potential employer. So we stopped." :)
Back to the open source / github resume idea. Great if your work is not in house, and you have no outside interests.<p>The recruitment industry is badly broken though.
