I applied through a recruiter. The process took 5 weeks. I interviewed at Meta (Seattle, WA) in May 2014
Interview
A recruiter reached out to me, but I didn't start the phone screen until four weeks later as I wasn't fully prepared. After I passed the phone screen, I was invited to onsite interview the next day. I went to their office two weeks later. After three week I was told that I didn't pass as I didn't do well in the system design round. The recruiter said as I had three years experience, so the position was a senior position, so the system design interview was really critical.
Interview questions [1]
Question 1
I forgot some of the coding problems, but here are what I can remember.
1. move all 0s to the front of an integer array.
2. given a target and a sorted array, find the highest value smaller than the target.
3. given a 0-1 matrix, find the largest graph that is 1-connected.
4. design a system that can quickly return public accounts' activity data. For example, how many persons like/comment Taylor Swift's status.
5. In culture fit round, was asked many questions about how and why did you make this decision, what would you do in this case. For example, why did you apply for grad school? why not go to industry after undergrad? Why did you choose your current company three years ago? Why did you move to this state? If at that time you also got an offer from FB, what would you do? Why FB?
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.
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.
