Meta (Facebook) Interview Prep: Coding Rounds Explained
How the Meta coding interview actually works in 2026: two problems per 45-minute round with no compiler to lean on, why speed and communication matter more here than anywhere else in FAANG, and the DSA topics that dominate: arrays and strings, hash maps, trees and BFS/DFS, intervals, and binary search. Includes a worked merge-intervals Python solution, a brief on the Pirate (system design) round for E4+, what the behavioral round screens for at each level, and a realistic preparation timeline.
