I was contacted by a recruiter from Facebook early August. After an initial phone screen with a mix of experience and technical questions, I was put through a 45 minute online interview where I was asked to talk about and optimise some code.
Following this interview I was connected with another recruiter who ended up handling my interview process from then on out. I had one or two more recruiter calls/interviews and then the onsite interviews were organised.
Although the position was for Menlo Park, I interviewed in Sydney. Four 45 whiteboard interviews in a row – two coding, one architectural and one on experience. Facebook provided a lot of useful material in preparing for the interview. I was quite surprised by the coding interviews, as they were not nearly as difficult as I was expecting.
I was asked to do one more online architectural interview, probably because I did not do so well on the onsite one.
Overall everybody was really nice, supportive and easy to get along with, which made the interviews fairly relaxed. The hardest thing about the process was just how long it was! The interviews themselves were really nothing like I had thought.
