El proceso duró 1 día. Acudí a una entrevista en Meta en ene 2011
Entrevista
The interviewer was very friendly, and we chatted some after he introduced himself and his projects.
He asked me to design and implement algorithms that correct typos, offering guidance, encouragement, and confirmation along the way. It felt really good to voice my thoughts along the way, and it helped him to know what I'm thinking.
He asked a few follow-up questions afterwords about my code (which I think he made up on the spot). I answered and we agreed on the answers.
Next, he presented a scenario that we formed a web startup featuring that code at its core. So then we discussed how to use more memory and less CPU, and how to scale up the company.
At the end I asked him his thought about fb and what he did before working there.
The experience was very fun.

Pregunta 1
Design and implement an algorithm that would correct typos: for example, if an extra letter is added, what would you do?
Took about a month from start to finish, which felt longer than I expected. After a couple of initial phone screenings, I faced a challenging technical round focused on system design. It was during this round that I was asked to describe overcoming a major career challenge. Interestingly, I had just reviewed a similar framework on PracHub, which helped me articulate my thoughts clearly. Overall, I appreciated the depth of the process and ended up accepting the offer.

Describe Overcoming a Major Challenge in Your Career
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.
