Solicité el puesto a través de un captador. Acudí a una entrevista en Meta en dic 2015
Entrevista
Contacted by recruiter, scheduled phone interview after a couple weeks. She setup a tech interview. The interviewer was very hard to understand and did not explain the problem well, when I would ask for clarification on certain parts I couldn't understand him. He only asked one question which you will see below. Unlikely to get call back:

Pregunta 1
Given two sorted input arrays which contain a two element array of [key, value], write a function which multiplies the two arrays together and sums them where the "key" matches. Example: "v1 = [[1, 3], [2, 4], [99, 3]]; v2 = [[2,3],[5,9],[99,1]]" results in "15". I first brute forced it with O(n*m) then used two pointers which resulted in O(n+m) then he asked me to write it in O(n log m). I could not think of an algorithm at the time for O(n log m).
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.

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.
