I applied through a recruiter. The process took 4 weeks. I interviewed at Meta (Menlo Park, CA) in May 2016
Interview
Don't waste your time with Facebook unless you're desperate. Like the other people mentioned here, there is something fishy going on with Facebook interviews. I really did well with the onsite interview and they told me that they passed on my application with no feedback after 2 weeks.
I've gone through two phone interviews and then an onsite interview with 3 coding (ninja), 1 design (pirate) and 1 cultural/coding (jedi) interview. I have heard that they usually do only 2 ninja interviews, but I got 3 for some reason.
The coding interviews are pretty standard. You either got it right or not. Explain everything clearly as you code it, because they may not understand your solution even if it's an optimal solution. Be prepared for follow up questions after that. Since I got the coding questions right, I got asked a second one each time. So on a successful interview be prepared to do 7 coding questions (again 5 in most cases).
Interview questions [1]
Question 1
I cannot go in specifics because of the NDA, but they are standard coding questions, which you can find on Leetcode or coding interview prep books.
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
