I applied through a recruiter. I interviewed at Meta in Nov 2015
Interview
I was contacted via email from my linkedin profile. A call was arranged and they asked a number of technical questions. The first section on systems was the most difficult for me as I didn't understand the question context well. Networking went better and the signals section was in between. They suggested that we move forward with the second interview in the series.
What is file descriptor 2 (this one had me confused as to what they were talking about - I thought it was about the internals of the file descriptor itself for some reason)
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
