Hello, I am a FB employee and I have created an interview prep guide for Facebook interviews, based on my and my colleagues' recent interview experiences. The guide has questions you should expect along with our answers that got us into Facebook. You can find it here: interviewjoy.com/services/interview-process-details/facebook-manager-job-interview-questions-answers-more/ (please do not forget to also look at the reviews at the bottom of that page). Thanks and good luck!
