I have received Production intern offer from FB, and while preparing for it I could not find many resources to prepare for the systems interview round. Hence, I decided to create my own preparation material. If you find any error, feel free to send a PR to improve the notes. I found these questions from this blog and I referred to OS book by Tanenbaum.
There are 2 rounds for PE internship, the first is the coding round and second systems round. In the coding round the questions are of easy to medium leetcode level. In the systems round, the main focus is to check the OS knowledge, with a particular focus on Linux based concepts. The following are the set of questions I had prepared, try to get an in-depth understanding of how and why a process is designed in such a manner.
