Fiz uma entrevista na empresa Meta (Menlo Park, CA).
Entrevista
My interview process consisted of six stages:
Initial Coding Interview
– Solved 2 loop-focused algorithm problems.
Second & Third Coding Interviews
– Two rounds, each with 2 algorithmic problems.
Behavioral Interview
– Discussed past experiences, teamwork, and problem-solving approach.
System Design Interview
– Designed a scalable architecture for a given scenario.
Follow-Up System Design Session
– Dug deeper into trade-offs and data modeling from the previous design.

After designing the system using Kafka, Flink, and ClickHouse, the interviewer asked how I would solve the problem without using any of those technologies, building everything from scratch. He gave me a generic queue and a generic database.
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.

Pergunta 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.

Given an array of strings, pick a subset whose concatenation contains no duplicate characters, and return the maximum possible length of that concatenation.
