Fiz uma entrevista na empresa Meta (New York, NY).
Entrevista
Overall, I found this to be a very challenging experience. I struggled with the majority of the material and concepts presented, which made it difficult to keep up at times. Many of the problems required a deep understanding of the underlying principles and strong problem-solving skills, particularly in areas related to algorithms and data structures.
In hindsight, I would highly recommend dedicating significant time to studying LeetCode (LC) and Logic Puzzles (LP) in advance. Practicing these types of problems regularly would definitely help build the intuition and technical foundation needed to approach the questions more effectively. With better preparation and familiarity, especially in algorithmic thinking and pattern recognition, I believe the experience would be much more manageable and rewarding.
In summary, while it was a tough challenge, it also highlighted key areas for improvement and emphasized the importance of consistent practice.
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.

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.

Pergunta 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.

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