I applied through a recruiter. The process took 3 weeks. I interviewed at Meta (Palo Alto, CA) in Apr 2011
Interview
A recruiter found my resume online and emailed me asking if I would be interested in opportunities with Facebook. We then spoke on the phone and she scheduled my first technical interview. Throughout the process the HR person was very friendly and helpful.
The technical interviews were conducted using Skype and collabedit.com. They consisted mostly of algorithms and data structures questions, and a few questions about projects I had mentioned on my resume. The first two interviewers were very friendly and positive, and I felt the interviews went very well, having answered all the questions correctly. The last interview was conducted by a grumpy engineer with a thick accent who was running 15 minutes late and sounded like he didn't want to be there. Unfortunately this put me off quite a bit, and I did not perform very well in that interview, 3 days later I heard back from HR that they wouldn't be proceeding with on-site interviews in Palo Alto.

Question 1
Print a singly-linked list backwards, in constant space and linear time.
Got a referral through a friend who worked at Meta, which sped up the entire process. After a casual initial chat, I went through a technical interview where I faced a DSA question about validating palindromes. The interviewer was friendly but rigorous. During prep, I had spent time with the coding challenges on PracHub, and it was funny to see a similar palindrome question pop up. Overall, I received an offer, but ultimately decided to decline it after careful consideration.

Question 1
Given a string s, return true if it can be a palindrome after deleting at most one character (Valid Palindrome II).
Recruiter call was pretty standard, first round was 2 Meta tagged LC mediums in 45 minutes. On-site was 2 coding sessions of 2 LC mediums, a system design interview and a behavioral interview with an engineering manager.

Question 1
How do you answer if someone asks how long a deliverable or project will take?
The entire process usually takes 3–8 weeks, depending on scheduling and the specific role. Coding interviews heavily emphasize common DSA topics such as arrays, strings, trees, graphs, BFS/DFS, heaps, hash maps, and dynamic programming. System design becomes increasingly important for E4+ positions.
