I applied online. The process took 3 weeks. I interviewed at Meta (Menlo Park, CA) in July 2024
Interview
For the first round interview, it starts promptly with a very short introduction. Then the interviewer will ask you two questions in which you will have around 20 mins to solve. You should discuss your solution with your interviewer before typing it out on coder pad. The interviewer will move on if you take too long to solve a question in order to give you equal time for both questions. If you use up all time you won't have any time to ask any questions at the end, so you should aim not to take up too much time on these questions.

Question 1
Given a 2d matrix, write an algorithm to navigate from the top left of the matrix to the bottom right of the matrix. The catch is that the matrix has some spots that are blocked in which you can't traverse that position. They can be represented as 1's vs open spaces can be represented as 0s. The solution should return the path as a list of coordinates (it should be in order of the traversal).
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.

Interview
It's honestly striaght from leetcode tagged
There are no surprises if you do tagged you would be good and do well.
System design is much harder. Would recommend using hello interview.

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.
