The process took 1+ week. I interviewed at Meta in Dec 2009
Interview
One word: disorganized. On more than one occasion, internal recruiters scheduled phone screens and failed to alert me that one had been scheduled, much less when it would be. Did not go past first technical screen, although I don't know if it was because of the scheduling issues or just the result of the first screen. Technical screen was reasonable.
Interview questions [1]
