Meta Developer interview questions

I applied through an employee referral. They have returned to me very quickly in mail with few questions regarding my background. Second interview was on the phone with HR recruiter. Also, background check and some easy technical questions. Third interview was video-screening with one of the employees. I've asked to write a code and answer algorithm question.

Applied through career fair. Got an on campus interview call after one week. Interview was scheduled 3 weeks after I got the email about being selected for the interview process. Facebook also hosted a dinner for all the people who were being interviewed.
