covering most of the behavior questions, it's not very hard if you have thought through. also including the analytical think part. i think the most important thing that this company looking for is thinking capability. learning capability is a must, otherwise you will be very painful.

I was contacted by a recruiter, followed by an interview and a writing test. The test was mainly about your language skills (for specific position) and problem solving for a specific case. About a week later, I was arranged an face-to-face interview with Facebook representative at their office. The questions are about your profile, your understanding of the job and your interest.
