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).

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.
Took about a month altogether, which felt longer given the intensity of the process. Kicked off with a technical screening, followed by two rigorous coding interviews. The DSA question on binary tree vertical order traversal hit me hard at first, but then I recognized the prompt instantly — I had just worked through something similar on PracHub. The final round was focused on system design, and while I ended up receiving an offer, I ultimately declined it. Overall, a challenging experience that definitely sharpened my skills.
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
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.
