I applied online. The process took 3 days. I interviewed at Meta in Sep 2014
Interview
Applied online. Got an email from a recruiter. Easy,efficient and painless process. The recruiters are really quick and will let you know the smallest of details regarding the interview.
Had a technical phone screen with an engineer from a similar team. Had to code on collabedit. Was initially asked some OOP concepts,Data structure questions.
The coding question was easy and i solved it correctly albeit a few corrections here and there. The code ran in O(n) with no space so i thought i did good. Question was find if one string is one edit distance away from the other string. This is the same as minimum edit distance question but with a twist. In this case you just want to know if its one edit away or not. The interviewer asked me if there was anything i could improve in the code, at that moment i did not think there could be any improvement other than some validation checks/readability of code. After the call i realized there was a small 5 line solution to this involving recursion but alas.

Question 1
Find if one string is "oneEditAway" from another string
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.
