I applied through a recruiter. I interviewed at Meta (Ciudad de México) in Apr 2016
Interview
I was contacted via mail, a recruiter saw my linked in profile, over the phone he had a few basic iOS questions, after that I had another phone Interview with "live coding" again, some iOS questions, this time not so basic and a few problems to solve in the editor. At the end I had an Interview in person with 4 different guys. Mainly solving code problems on a whiteboard and few general questions. One of the interviews was about Architecture, that one was the toughest for me, because I never did something like that, In general I never had an Interview process like this.
Interview questions [1]
Question 1
Don't recall all the questions, but some of the questions had to do with general programming patterns and memory usage, and the problems were mainly about knowing algorithms and complexity with Big O notation, stuff like that
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.
