One phone interview followed by one on site. Three rounds at the on-site interview plus a reception period and a lunch interview which were not evaluative. Facebook has Ninja and Jedi interviews. Ninja = coding interviews. Jedi = 1 behavioral interview and if candidate is not experienced, half way through the interview you may be asked another coding question. Ideally Jedi interviewer is an experienced employee.

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.
