I applied through a recruiter. The process took 3 weeks. I interviewed at Meta in Dec 2014
Interview
HR approached me via email, asked to tell a little bit about my self, and what is my strongest programming language, sent me a mail with pointer where to learn from.
An phone Interview was set up for 3 weeks later.
it was on collabedit.com with skype. the interviewer was very nice, asked to talk a little bit about what I do.
asked one question.
if you need to implement bool Find(string str) which finds if a string exists in a dictionary
describe the data structure you will use.
a.write how one node of it will look like,
b. implement the function and add support for "?" wildcard which can return more than once.

Question 1
I said suffix tree is the best way to go, so he asked me how will a node of that tree will look like?
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.
