I applied through an employee referral. I interviewed at Meta in Feb 2016
Interview
Three rounds of phone interview. First two rounds are technical interviews, the final round is team match. The HR is very quckly in given feedback. Normal he will notify you whether you will have another round the same day of the phone interview.

Question 1
Round 1:
tree traversal problems.
1) Given a tree structure, print the preorder sequence of the tree or postorder sequence of the tree. 2) Given a sequence, construct a binary tree from it.
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.
