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.
Interview questions [1]
Question 1
The second ninja (coding) test was about event processing system using pulling model, which literally no one in the industry is using.
The technical round hit me with a classic array manipulation problem: moving zeroes to the end without disrupting the order of non-zero elements. As I tackled it, I felt a wave of familiarity wash over me; I had just practiced a similar challenge on PracHub. The rest of the interview followed a straightforward path, with some easy behavioral questions sprinkled in. Overall, it felt very easy, but I wasn’t quite the right fit for what they needed, so I didn’t receive an offer.

Question 1
Move zeroes in an array to the end while keeping non-zero element order, in place
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
