The interview process was pleasant. I had four interviews, 1 half coding and half cultural fit, one design, two coding interviews. None of the coding questions was difficult. The recruiter sent you links for coding preparations. If you did you homework, then you would have seen the questions there. I had the feeling that they wanted you to code fast, neat and bug free.

Question 1
The design interview process was a little difficult. I kept saying my thoughts. However, the interviewer was silent most of the time. I didn't get much hint on which directions to go.
I applied through a recruiter. The process took 2 weeks. I interviewed at Meta (Menlo Park, CA) in Nov 2012
Interview
I met the recruiter in an event hosted by the university, and then send her my application. In one week, they schedule an interview for me.
It was 1-1 phone interview, purely technical. The interviewer asked me some small algorithm problems, and then asked me to write code. Sometimes they will ask you to optimize your first solution and, also, write the optimized code. They are very friendly, it's ok to ask for some hints and fix some minor bugs in code.
I had two phases of interviews, same style, and then got the offer.
