I applied through an employee referral. I interviewed at Meta in Dec 2014
Interview
Met Facebook engineers who referred me to the recruiter. The recruiter contacted me three weeks after I met the engineers. Set up round 1 phone screen within the next 2 weeks of our first email exchange. Facebook does move pretty fast with the recruiting process. The recruiter contacted me again about 2 days after round 1 interview to set up round 2. Round 2 was about 3 weeks after round 1.
