I applied through an employee referral. The process took 1 week. I interviewed at Meta in Mar 2012
Interview
A friend of mine working there referred me to the recruiter. The recruiter promptly contacted me to set up a phone interview and asked me what I want from my career and if I like fast paced working environment. Everything was very smooth and professional.
The phone interview lasted about an hour and I was asked to write codes on some collaboration editing web site like google doc.
The problem to solve and a couple of function headings were already given in the web page.
The question was about the binary tree. I was supposed to write a function to return the next node in inorder traversal sequence. In itself, it looks complicated but, there was a funciton heading called, init(), that you can use to preprocess and add any data structure you need.
I somehow missed this initially and found this too late :(

Question 1
write an iterator function that returns next node in inorder traversal sequence in binary trees. You can write an init() function to initialize what you need
Took about a month altogether, which felt longer given the intensity of the process. Kicked off with a technical screening, followed by two rigorous coding interviews. The DSA question on binary tree vertical order traversal hit me hard at first, but then I recognized the prompt instantly — I had just worked through something similar on PracHub. The final round was focused on system design, and while I ended up receiving an offer, I ultimately declined it. Overall, a challenging experience that definitely sharpened my skills.
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.

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