I applied through an employee referral. The process took 2 weeks. I interviewed at Meta (Menlo Park, CA) in Jan 2014
Interview
Overall the process is very fast and all the interviewers are very nice.
It take 3 weeks to finish all the interviews (include christmas and new year holidays).
I took 1 phone screen + 2 coding + 1 system design + 1 research interview( for PHD ).
All the coding questions are the common questions you could meet them easily when you read " crack the coding interview" or surf GeeksforGeeks.com, and there was no brainteaser.
The system design problem is kind of hard, because there are no right or wrong answers. I think I didn't perform that well in this round, because I am not very experienced in large system design.
The research interview mainly focus on my research project, and we also had a small coding part, I did well on that.
Honestly, I am kind of surprise that I did not get offer from Facebook, maybe there were some requirements that I did not match.

Question 1
Overall Facebook's interview questions are interesting and not hard. All the interviewers are knowledgable and nice to talk to.
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.

Question 1
Given a string, determine if it is a valid palindrome considering only alphanumeric characters and ignoring case.
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.

Question 1
Design Twitter and consider if it was suddenly an extremely low latency env
Grateful doesn't even begin to describe how I feel about landing this role. The interview loop was smooth and friendly. They kicked things off with a technical round where I faced a DSA question about verifying an alien dictionary. Lucky for me, the time I'd spent on PracHub paid off, as it had the same type of problem just days before. After that, I had a system design discussion and a behavioral interview. Everything felt very collaborative, and by the end, I received an offer that I was thrilled to accept.

Question 1
Given a list of words written in an alien language and the order of letters in that language's alphabet, determine whether the words are sorted lexicographically (Verifying an Alien Dictionary). Walk through the comparison approach using a character-to-index map, the O(C) time complexity where C is total characters, and how you'd extend it to handle words with mixed-case letters or words containing characters outside the given alphabet.
