J'ai postulé en ligne. Le processus a pris 2 semaines. J'ai passé un entretien chez Meta en mars 2015
Entretien
I applied throw the Facebook career website. The process took about 2 weeks and consisted of a questionnaire, a phone call with the recruiter, and 45 minutes interview by phone (phone screen). All the process took place mostly by email. In addition, couple of days before the interview the recruiter invite me to an online video session with other applicants.
Questions d'entretien [1]
Question 1
Given a string of digits, where every digit represents a letter (1->a, 2->b, 26->z). Find the number of words that we can generate from that string.
For example:
123 -> abc, lc, aw. The answer: 3
456 -> def. The answer: 1
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.
