I applied through a recruiter. The process took 4 weeks. I interviewed at Meta in Oct 2013
Interview
Received message via LinkedIn for an interview, shortly after replying a quick phone call was set up to determine what my interests were and how it aligns with the work available at Facebook. After that, a phone interview is done to screen candidates, the phone interview involves actual coding done using a shared online notepad. Then an in person interview is done which consists of 4 interviews (algorithms - system design - class design/algorithms - behavioral). There is also a break where you can ask an engineer any questions regarding the company. Results come back in a week after the in person interview.
Interview questions [1]
Question 1
signed NDA so cannot discuss. But do prepare for sorting, pattern matching algorithms, design problems such as how to go about implementing certain features in Facebook, and review previous work experience for some stuff to talk about in depth during behavioral interview.
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.
