I applied through an employee referral. I interviewed at Meta in Dec 2018
Interview
Got a link to an online challenge with a medium level LeetCode problem (Product of Array Except Self) to solve in 20 min. Thankfully, I have done this problem before.
After that the recruiter scheduled a phone screen with an engineer. After we chatted about the role for 10 min, jumped into coding question which was to write an iterator (in Java) for a list of lists of integers.
Even though I was able to write good code before the end of the session and there was a good conversation, recruiter said NO the next day.
Perhaps Facebook is looking for VERY gifted individuals that can figure out very difficult problems without breaking a sweat and that is certainly not me.
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.
