I applied through a recruiter. The process took 8 weeks. I interviewed at Meta (Seattle, WA) in Aug 2016
Interview
Overall, the process was straight-forward, but a bit slow in turnaround. I had been contacted by one of the recruiters every 2-3 months for the past year or so, and just had to give the go-ahead. Every round of scheduling seemed to take a week, and then getting feedback was another 3-4 days minimum, then another week until the next interview.
The process is straightforward and designed to help us get to know each other. It moves through a few stages at a comfortable pace, involves conversations with several team members, and focuses on making sure it's a good mutual fit.

Interview
Had an initial recuriter call and then scheduled a coding round with 2 leetcode questions. Practicing Meta-tagged leetcode questions would help prepare for this round. Interviewers expect clear communication and code.
Generic LeetCode-style questions, many tagged as Meta, so extensive preparation is required to perform well in the technical interview. The experience varies significantly - some interviewers provide hints and guidance, while others expect candidates to solve problems independently with minimal assistance.
