Solicité el puesto a través de un captador. Acudí a una entrevista en Meta (Menlo Park, CA) en oct 2015
Entrevista
Standard facebook interview process. I already had an offer from another big company and told the recruiter. He went about the process really fast. 1 phone interview. 4 technical onsite interviews. (3 coding and 1 system design). Very school like questions. Could answer everything except the system design. I could not connect with the interviewer which I feel is important for design questions and he was not verbose enough to explain the basic requirements of the system.

1. Design a web crawler with fixed set of resources. (design)
2. Serialize/deserialize graph. 3. Check if tree is a mirror image. (Left and right is same)
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.

Pregunta 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.

Pregunta 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.
