I applied through college or university. The process took 3 weeks. I interviewed at Meta (Menlo Park, CA) in Nov 2015
Interview
on campus at Menlo Park, which is called Facebook University Day. 45min technical interview, code on white board. After that we had a wonderful tour of Facebook Campus and had a lunch. The ice-cream was super good! After that, Facebook Engineers made presentations and lectures about how it feels to work at Facebook.

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.
