Meta Developer interview questions

Interview process was rigorous but fair, emphasizing data structures, algorithms, and system design. Interviewers were professional, collaborative, and focused on problem solving, communication, and coding clarity throughout the entire experience.

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!
