I applied online. The process took 2 months. I interviewed at Meta in Jan 2016
Interview
2 rounds phone Skype interview, each round lasted from 45 mins to 50 mins. The difficulty was average, hadn't met tough questions. The recruiter replied promptly and helped me a lot. The interviewers were kind and helpful, gave me hints during the interview. Got offer one week after the second round and I accepted it without doubt.
Interview questions [1]
Question 1
Behavior: past project and what's the funest thing in it.
1. Erase duplicate in an unsorted array
2. Average value by level in a tree
3. minimum size subarray sum
4. BST vertical order sum
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.
