I applied through college or university. I interviewed at Meta (Seattle, WA) in Mar 2019
Interview
First part is a 20 question multiple-choice quiz that you have to complete in 18 minutes. The quiz covers basic linux commands, operating systems concepts, and networking. Very basic questions.
Then its a 45 min algorithm interview over phone, with coder pad. Pretty easy questions. I got goat Latin and dinosaur CSV parsing question.
The second interview is also over the phone and is an open-ended discussion with the interviewer. He/she asks questions about operating systems and debugging Linux systems. They go deeper and deeper into concepts until you don't know what is going on. Study Operating Systems fundamentals and tools to debug Linux systems (top, vmstat, dstat, sys trace, etc.).
I applied through a recruiter. I interviewed at Meta (Sunnyvale, CA)
Interview
Pretty straightforward. I interviewed for the PE University Grad role. The first round was mainly a basic coding round and a PE basics round. Once I passed that, there was a loop of 3 interviews - System round (focussed on OS concepts), another coding round and a behavioral round.
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
