I applied through university. The process took 4 weeks. I interviewed at Meta (Menlo Park, CA) in Oct 2012
Interview
I had one phone interview, before I was invited to on-site interview on their new office in Menlo Park.
They paid for all the expenses incurred during the trip (hotel, transportation, food, and any other non-personal expenses)
The on-site event lasted from 9 am to 4 pm. It started with a breakfast on one of their micro kitchen located on every floor of their building, and soon after the breakfast every candidate was taken to a room where they took three 45-minutes interview with Facebook engineers. One was behavioral, and 2 were technical.
In a behavioral interview, interviewer will look at your resume and ask you couple of questions related to it, so make sure you are able to talk about whatever you put on your resume.
Two technical interview is mainly coding on a whiteboard. They will ask some basic question like "why did you choose Facebook" at the very beginning, but the majority of your time there will be spent coding on a whiteboard.
After the interviews, candidates are taken to a lunch on one of the cafeteria on their campus. I really loved the food there, and they have lot of different choices (Italian, Chinese, grills, ...).
After lunch there was 45-minute tour around the Facebook campus.
The event concluded with two tech talks (one backend and one frontend) and Q&A session
Overall it was a great experience.

I am not allowed to share questions here (signed NDA)
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.

Question 1
Given an array of integers and a target value, return the indices of two numbers that add up to the target
Unexpectedly, the first question in the technical round felt familiar. It was about finding a subset of strings with unique character concatenation — same problem I had worked through on PracHub a few days earlier. The interview included a recruiter screen followed by a rigorous pair of technical interviews where I tackled data structures and algorithms alongside system design concepts. After successfully answering a few more challenging DSA questions, I received an offer. The entire experience was intense but ultimately rewarding, and I happily accepted the position.

Question 1
Given an array of strings, pick a subset whose concatenation contains no duplicate characters, and return the maximum possible length of that concatenation.
Standard cookie cutter interview with a coding interview, a system design interview and culture interview. The coding part is basically leetcode. The system design is what you can find on many youtube videos. The culture one is more tricky as they want to see that you fit Meta's culture, not that you were doing great at your existing company. So skills like dealing with conflict without calling in managers is sought after.

Question 1
coding: I forgot, sorry
system design: design ticketmaster
culture: talk about past project; when you disagreed with a peer; how I resolved dissagreements, etc.
