I applied through a recruiter. The process took 4 weeks. I interviewed at Meta in Jan 2024
Interview
Recruiter reached out to have a quick conversation about potential interest, and initial phone screen was set up about 10 days from then. 2 coding questions in 40mins. Once screening was cleared, the recruiter set up a final round of interviews (4 interviews divided across 2 days). All interviewers were nice. Coding questions were not too difficult but there's always pressure to finish coding a problem in about 20mins to do well. All coding and behavioral rounds went very well, but I certainly did not do well on the Design interview.

Question 1
Largest common substring, dynamic programming (sentence using dictionary), custom data structure with constant time insert, lookup, recall
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.

Question 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.
