J'ai postulé en ligne. Le processus a pris 1 jour. J'ai passé un entretien chez Meta (Philadelphia, PA) en janv. 2016
Entretien
I applied online and about a month later was emailed asking to set up an hour long phone interview. Phone interview was between myself and a Facebook engineer while we were on a program that allowed him to see me code in real time. Was emailed a few days after phone interview by recruiter to tell me they were not going to pursue any further.

Question 1
A museum was represented by a square matrix that was filled with O, G, and W where O represented open space G represented guards, and W represented walls. Write a function that accepts the square matrix and returns another square matrix where all of the O's in the matrix are replaced with the number of how many spaces they are away from a guard, without being able to go through any walls.
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.

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.
