I applied through an employee referral. The process took 2 months. I interviewed at Meta (Menlo Park, CA) in Oct 2016
Interview
2 phone screens, 6 hour on-site, transferred to another team, 3 hour on-site. The questions were repetitive between interviewers and were more hypothetical/behavioral. Most were pleasant but some interviews felt scripted and forced/awkward.
Interview questions [1]
Question 1
Explain what happens in the back-end network when you use Facebook.
