The process took 2 weeks. I interviewed at Meta (Palo Alto, CA) in May 2009
Interview
Interview consisted of a phone interview and then an all-day on-site interview with four one hour interviews. I was really impressed by the difficulty of the questions that they asked and the level of thinking and coding they expected. After the interview, I wasn't sure if I would be happy working at facebook so they let me come back and speak with me would-be manager and director as well as some coworkers so I could make a good decision.
Interview questions [1]
Question 1
... be prepared to write real code on a while board on on-line editor.
The technical round hit me with a classic array manipulation problem: moving zeroes to the end without disrupting the order of non-zero elements. As I tackled it, I felt a wave of familiarity wash over me; I had just practiced a similar challenge on PracHub. The rest of the interview followed a straightforward path, with some easy behavioral questions sprinkled in. Overall, it felt very easy, but I wasn’t quite the right fit for what they needed, so I didn’t receive an offer.
