Me postulé a través de un reclutador. Acudí a una entrevista en Meta (Menlo Park, CA) en ene 2026
Entrevista
got a dm from a meta recruiter on linkedin. process was super fast. initial recruiter screen was the usual - background and checking alignment on level (e4/e5). then a technical phone screen with two lc style coding questions, mostly mediums around arrays and strings.
the onsite was 4 rounds total. first was a coding round (traditional ds/algo stuff), then sys design where i had to design a real-time collaborative editor - really had to watch out for concurrency and scaling - they keep talking about it. third was leadership & drive, mostly situational stuff like handling conflict or project tradeoffs. the most interesting one was the new ai-assisted coding round. it's not like leetcode - you’re working in a real codebase with multiple files and an ai sidebar. had to build a feature into an existing structure and honestly, it’s tricky because you have to critique the ai output and not just blindly copy it lol. i was a bit shaky on the system design and how to actually 'collab' with the ai without looking like i was cheating, so i did a few mocks on prepfully with a meta swe. that helped a ton with my structure and how to pipeline my thoughts while the ai was generating code so i didn't just sit there idle. got the offer 2 weeks later, team seems great so far!

Given an array of strings, write a function to return all strings that are anagrams.
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.
