I applied through a recruiter. The process took 4 weeks. I interviewed at Meta in Mar 2016
Interview
It's very straight forwards, after chatting with HR. There are two rounds phone interview, which are focus on coding and system, respectively. And finally it's the on-site interview. I reached the system interview and failed. The whole process can move forward fast and slow, which depends on the candidate's requirement.

Coding is the basic algorithm coding challenging. System interview will ask more details questions regarding with Linux and networking, like what happens when you typed 'ls' in the terminal.
I had two screening rounds and 3 interview loop rounds, Meta leetcode questions, systems design can be extensive. Questions can be repeated so look out for all the available questions online. Systems debugging is a very important topic
