Pretty straightforward interview process - screener interview followed by a 4 interview loop. Facebook uses the loop to do two standard algorithms/data structures technical interviews, one manager/fit interview and one "design" interview which I misunderstood to mean user facing design, but instead is more of an architecture, big box drawing exercise.

Question 1
Asked to design a system for facebook chat messaging. Difficult since I hadn't had any backend/distributed systems experience.
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.
