Fog Creek started out doing phone screens and then in person interviews. The phone screens cut down on a lot of false positives, but we'd still have people come in, get picked up by the limo, stay two nights at the Ritz in Manhattan, and then come in for an interview and get 3 straight NO HIRES in a row. We added a screen sharing code interview in the mix, and saved *so* much time and money. Highly recommended. (We use Copilot and Etherpad to do the remote code interview).
