My cpi was 7.94 then he asked me 2 technical questions 1 is from DS and other is from OS. He had very deep knowledge of OS. 6-Take any of your favorite of Data structure and asked me to explain it. But when I start explaining him and he interrupt's me just after 30 sec and said leave it. By this he wants to check how fast I can make a decision and also his main focus was on my confidence rather than asking any question. So guys be confident. 7- And it was the toughest and last technical question of my interview around 10-12 min discussion over it. He said if I kill any of the child process in windows using windows Task Manager then how it will affect its parent process ie what happens whenever you kill a child process in windows.
