How To Hire by Wall Street Journal

"For every complex problem there is an answer that is clear, simple, and wrong." - H.L. Mencken

Freelancers are a good bet for small companies and also for side-projects. All Hail the Freelancers. But that rule about candidates who worked at a large business is not reasonable.
