I applied through a recruiter. The process took 4 weeks. I interviewed at Meta in Jan 2015
Interview
Facebook recruiter got in touch with me. Had a phone conversation with her. She setup a phone screen within a week. Used Collabedit for coding. Two questions. Got a reply back within a week. Setup on site for the next week. 1 behavioral, lunch, 2 coding, 1 system design. The questions I got were weren't super difficult except for the system design question (how will you design the social graph with class, interfaces, etc). Other questions were, implement Pow, convert from decimal to roman and vice versa, binary tree serialization and deserialization, implement concurrent read/write buffer. For the system design question, the interviewer was very helpful and provided hints when I got stuck.
Generic LeetCode-style questions, many tagged as Meta, so extensive preparation is required to perform well in the technical interview. The experience varies significantly - some interviewers provide hints and guidance, while others expect candidates to solve problems independently with minimal assistance.
Spoke with interviewer over video conferencing. He was very communicative . He answered my questions. Asked me BFS question. A question that involved BFS search. Given a matrix, I am suppose to find a path from top left to down right.

Question 1
A question that involved BFS search. Given a matrix, I am suppose to find a path from top left to down right.
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.
