We had four rounds of coding interview and one of them is behavior interview. The interviews mainly focus on basic data structure and algorithm questions. After the interviews, they took us for a lunch, and a tour of Facebook HQ.

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.
