I was originally contacted via e-mail by a recruiter and then initial phone screen with recruiter by the following week. I had a 45min sql interview with the team member that involved just a couple of medium hard SQL questions and questions regarding previous experience.

Was a mix of technical and non-technical interviews. Great culture. Interviewers were very friendly. The interviews were more of a discussion than one sided questioning. Interviewers were also patient to answer how it is to work at Facebook, and how one can grow their career.
