I applied through college or university. The process took 4 weeks. I interviewed at Meta (San Francisco, CA) in Nov 2015
Interview
I applied through Career Fair in College and got called for on-campus interview. After 2 weeks, the interviewer notified me to go for an on-site interview. I chose San Francisco, at the headquarter of Facebook. The first question is easy when you only have to dfs or bfs to find all adjacent areas. The second question took place at the on-site, and it was a little bit harder than first one
Interview questions [1]
Question 1
Given a 2-d matrix with each cell contains a character from the alphabet. Given a word, verify if the exist in this matrix. A word is called to exist in a matrix if there is a path from cells to cells in the matrix and this path creates a word that matches the word we're looking for. a cell could move to all vertex-adjacent cells (so there are 8 adjacent cells) and cannot use a cell more than once
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.

I applied online. I interviewed at Meta (Menlo Park, CA)
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.
