LinkedIn organized a recruitment process in our campus recently. There was an online test of duration 90 minutes with around 30 multiple choice questions and 3 coding questions. Multiple Choice questions included questions from Data structures, DBMS, OS and Computer Networks. The 3 coding questions were of easy level. I was able to solve only 2 of them, still I cleared the written round. Next round was skype interview. He asked field of my interest and then started with it. First we started with operating system - questions about paging, swapping, what is virtual memory etc. Then Computer Networks - What is difference between tcp/udp, which one is used in live streaming and paid subscriptions. How connection is established between nodes etc. In Java, he asked me the internal working of garbage collector and finally how B-Tree works internally and need of threading. All the topics discussed were of my choice and interviewer frankly asked if i was uncomfortable with any of them. He drilled down each question to the finest level, which at times confused me and i had to change my answers. I was not prepared about what will be asked during interview so the whole session was awful for me. This interview was to be followed by final onsite interview in Bangalore but i since i couldn't clear this round, i never got a call.
