I applied through an employee referral. The process took 2 months. I interviewed at Meta (London, England) in Nov 2014
Interview
Facebook employee referred me : 1 telephonic round + 4 onsite (1 Cultural fit + 1 Design + 2 Coding). The interview process was very smooth and all the interviewers were very friendly. Most of the questions in the coding round were on algorithm fundamentals. Also they expect clean coding with proper testing. The design round is more like the discussion you would have with your teammate suggesting pros and cons of each method.

Question 1
Clean code, test cases, scalable design, high level design...
1 leetcode med, 1 leetcode hard. make sure you know your DSA and leetcode questions. I wasn't able to get an offer bc i didnt complete the second question. Got a reply 2 days later saying they would move on
Overall, the process took a little over two weeks, which felt a bit longer than I anticipated. After a quick screening, I went through two technical rounds focusing on coding and DSA concepts. One of the questions was a classic palindrome check; mid-way through, I realized it was something I had practiced on PracHub just days earlier. The final step was a casual behavioral interview. I was relieved to get an offer shortly after, which I happily accepted.
