I applied online. The process took 3 weeks. I interviewed at Meta (San Francisco, CA) in Nov 2015
Interview
Applied online after talking to a recruiter at a career fair, had an interview on campus and went to final round interviews during their "University Day." The process was fairly quick and the recruiters really make you feel welcome during your tour of facebook. There was a presentation about what an internship at facebook was like and lunch from their cafeteria. Each person gets their own individual interviewer and was taken to one of the many rooms in the building for their interview. There are 2 interviews total before you are given a decision.
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.

Coding interviews heavily emphasize common DSA topics such as arrays, strings, trees, graphs, BFS/DFS, heaps, hash maps, and dynamic programming.
