I applied through a recruiter. The process took 4 weeks. I interviewed at Meta (San Jose, CA) in Sep 2017
Interview
1 phone screen and 4 rounds of on-site interviews. The phone screen question was a simple programming question, the questions on-site were far more difficult. All the interviews required live coding.

Question 1
Regex string matching implementation for a particular set of patterns
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.
I applied through a recruiter. I interviewed at Meta
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.
