I applied through a recruiter. The process took 3 days. I interviewed at Meta (Palo Alto, CA) in Jul 2010
Interview
A recruiter called me to see if I'd be interested in a job on the applications engineering team at Facebook. After an hour long conversation, he asked me 10 basic unix questions like "Tell me the command to display the routing table." and then submitted my answers to the hiring manager. I then did a followup interview where they wanted to bring me in for another interview. The only problem was that they wanted me to write syntactically correct code on a whiteboard for an hour. Given that I'm not a programmer and I have a job with better benefits than Facebook, I declined the offer.
