I applied through a recruiter. The process took 1 day. I interviewed at Meta (Seattle, WA) in Nov 2014
Interview
1 Behavior/Past experience
2 Ninja
3 Lunch (not rated)
4 Design
5 Ninja
The behavior interview is about 1 hour, just talking about your past and current experience and projects you have done, plus a 15 mins coding test.
first Ninja is an opening question, essentially creating your own question based on a scenario and do some coding. My experience was really good so you have the flexibility to design questions you are familiar with.
Lunch was chat with a senior team lead, relax and get to know what you want to know.
Design was easy for me, since I have done a similar system at my current job.
the last ninja really sucked, the question is about a really unconventional event processing model using "pulling" instead of standard "push" model (like Storm), and the interviewer does not talk much and was not happy when I proposed the much simpler and intuitive push model. I failed on this one.

Question 1
The second ninja (coding) test was about event processing system using pulling model, which literally no one in the industry is using.
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.
