I applied for the position and quickly received a response that they were interested (about 1 day). They informed me that there was first a technical interview, then if I passed that, they would schedule a second culture/fit interview. Facebook provides access to a sponsored interview prep session by Gayle McDowell (author of "Cracking the Coding Interview") which were provided on a twice-a-week basis indefinitely, in in-person and online form. From this point on it was clear that they are very interested in churning through interview candidates at a rapid pace. I scheduled an interview a week after their contact, and ran prep (LeetCode.com offers a lot of questions in the style of their whiteboard tech interview) as much as I could. There were three other candidates in the lobby at the same time as me. I can only assume that there are as many as a couple dozen interviews done daily at this rate (they were scheduled 15 minutes before me). The technical interview is scheduled for a pretty tight (not hard, but they will stop you) 45 minutes. You'll get asked some sort of non-linear algorithmic question, and you MUST FOLLOW THE INTERVIEW PREP INSTRUCTIONS PRECISELY. One of the options for blueprinting out your solution is to maybe toss some pseudocode up explaining your algorithm - I did it a little while trying to explain and got dinged for "jumped to coding right away." As far as I can tell, they go through enough candidates that they can be extremely picky with their technical selection - ace it, you're golden. One misstep and you're chopped liver.
