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
Design Twitter and consider if it was suddenly an extremely low latency env
Grateful doesn't even begin to describe how I feel about landing this role. The interview loop was smooth and friendly. They kicked things off with a technical round where I faced a DSA question about verifying an alien dictionary. Lucky for me, the time I'd spent on PracHub paid off, as it had the same type of problem just days before. After that, I had a system design discussion and a behavioral interview. Everything felt very collaborative, and by the end, I received an offer that I was thrilled to accept.

Question 1
Given a list of words written in an alien language and the order of letters in that language's alphabet, determine whether the words are sorted lexicographically (Verifying an Alien Dictionary). Walk through the comparison approach using a character-to-index map, the O(C) time complexity where C is total characters, and how you'd extend it to handle words with mixed-case letters or words containing characters outside the given alphabet.
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
