I applied through an employee referral. The process took 2 weeks. I interviewed at Meta in Dec 2010
Interview
I was first called by a FB recruiter and we chatted about 15 min about my general background information.
I then was followed up with a phone interview with a FB engineer. He seems to be an experienced engineer. He started with a common background question like challenge of current project. Then, he asked me to design the Facebook Credit system. I proceeded with talking about I would started with designing the backend of the system, for example a ER diagram that would outline the relationship between existing user information and the new information related to the FB Credit system. I was a little nervous at the beginning, but the interviewer jumped in and gave me some help. He then asked me how would the total credit points of a user be calculated based on my design. For that question, I answered how the data is delivered to user from end to end in a multi-tiered web application. Next is the programing question (write a function to convert an ASCII representation of a positive integer to it's numeric value). I had a subtle bug in my code, but in general I got it right. I coded in PHP, the interviewer is satisfied with it since FB uses lots of PHP. The last 5 min was for me to ask him some questions.
The interviewer was very professional and helpful during the interview. He was able to follow my thoughts and provide hints.

The technical round hit me with a classic array manipulation problem: moving zeroes to the end without disrupting the order of non-zero elements. As I tackled it, I felt a wave of familiarity wash over me; I had just practiced a similar challenge on PracHub. The rest of the interview followed a straightforward path, with some easy behavioral questions sprinkled in. Overall, it felt very easy, but I wasn’t quite the right fit for what they needed, so I didn’t receive an offer.

I applied online. I interviewed at Meta (Menlo Park, CA)
Interview
It's honestly striaght from leetcode tagged
There are no surprises if you do tagged you would be good and do well.
System design is much harder. Would recommend using hello interview.
