J'ai postulé via la recommandation d'un employé. Le processus a pris 2 semaines. J'ai passé un entretien chez Meta en déc. 2010
Entretien
I was first called by a FB recruiter and we chatted about 15 min about my general background information.
I then was followed up with a phone interview with a FB engineer. He seems to be an experienced engineer. He started with a common background question like challenge of current project. Then, he asked me to design the Facebook Credit system. I proceeded with talking about I would started with designing the backend of the system, for example a ER diagram that would outline the relationship between existing user information and the new information related to the FB Credit system. I was a little nervous at the beginning, but the interviewer jumped in and gave me some help. He then asked me how would the total credit points of a user be calculated based on my design. For that question, I answered how the data is delivered to user from end to end in a multi-tiered web application. Next is the programing question (write a function to convert an ASCII representation of a positive integer to it's numeric value). I had a subtle bug in my code, but in general I got it right. I coded in PHP, the interviewer is satisfied with it since FB uses lots of PHP. The last 5 min was for me to ask him some questions.
The interviewer was very professional and helpful during the interview. He was able to follow my thoughts and provide hints.

Question 1
Design the Facebook Credit system which is a application where users can buy/trade virtual currency and can use the virtual currency to purchase Facebook services, like paid apps.
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.
