I applied through a recruiter. The process took 3 days. I interviewed at Meta (São Paulo, São Paulo) in Feb 2014
Interview
It's a long process but it is very clear. Starts with one skype interview about general things, a second skype interview about coding. Then if everything goes well an on-site set of interviews (4 in total) about different aspect (cultural, coding, design).
The last set is kind of extenuating, in all exercises there is always something more to add to the solution.
I finally didn't get the job because of the result of one of these interviews

Question 1
Design how to use 1000 bots to crawl wikipedia with some restrictions
Got a referral through a friend who worked at Meta, which sped up the entire process. After a casual initial chat, I went through a technical interview where I faced a DSA question about validating palindromes. The interviewer was friendly but rigorous. During prep, I had spent time with the coding challenges on PracHub, and it was funny to see a similar palindrome question pop up. Overall, I received an offer, but ultimately decided to decline it after careful consideration.

Question 1
Given a string s, return true if it can be a palindrome after deleting at most one character (Valid Palindrome II).
Recruiter call was pretty standard, first round was 2 Meta tagged LC mediums in 45 minutes. On-site was 2 coding sessions of 2 LC mediums, a system design interview and a behavioral interview with an engineering manager.

Question 1
How do you answer if someone asks how long a deliverable or project will take?
The entire process usually takes 3–8 weeks, depending on scheduling and the specific role. Coding interviews heavily emphasize common DSA topics such as arrays, strings, trees, graphs, BFS/DFS, heaps, hash maps, and dynamic programming. System design becomes increasingly important for E4+ positions.
