I appeared through college.The first round was an aptitude in which there were two sections general intelligence and technical. Inspite the section was technical all the questions were based on logic and puzzels. The next round was technical round in which they asked me the questions about OS that how can interprocess communication occur, what are the types of memories in a process and questions about computer network that where are the servers located,can we track the location about the server and the commands.They asked about how can we track to the previous element in singly linked list. They don't actually look for good communication skills. I was rejected inspite of having good communication skills because they tried to confuse me and i was unable to recall some of the concepts.
