I applied through a recruiter. I interviewed at Meta (Menlo Park, CA) in Oct 2015
Interview
Standard facebook interview process. I already had an offer from another big company and told the recruiter. He went about the process really fast. 1 phone interview. 4 technical onsite interviews. (3 coding and 1 system design). Very school like questions. Could answer everything except the system design. I could not connect with the interviewer which I feel is important for design questions and he was not verbose enough to explain the basic requirements of the system.

Question 1
1. Design a web crawler with fixed set of resources. (design)
2. Serialize/deserialize graph. 3. Check if tree is a mirror image. (Left and right is same)
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.

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.
