Me postulé a través de una facultad o universidad. El proceso tomó 1 día. Acudí a una entrevista en Meta
Entrevista
I faced three 1 on 1 interview rounds, each with one coding question.
Round 1: Given an undirected graph and a node, modify the graph into a directed graph such that, any path leads to one particular node.
Round 2: Given a matrix of size mXn, and a list of cells, find the number of paths from the top left cell to the bottom right cell.
Round 3: Solve a linear equation in one variable, where the possible operands are +,- and * along with brackets. For eg. (2x + 5 - (3x-2)=x + 5)
The interviewers themselves were very helpful, prodding me towards the right answer, and it was a good experience overall

The questions weren't tough as such, I fumbled a bit with the code for the matrix question which i guess could have been handled better.
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.
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.
The interview felt more straightforward than I anticipated for a well-known tech giant. After a recruiter screen, I faced a technical round that included a DSA question about finding the lowest common ancestor in a binary tree. I was pleasantly surprised when I realized the exact problem had popped up in the algorithm practice section on PracHub during my prep. Ultimately, the experience was decent, but I chose to decline the offer as it didn’t align with my current goals.
