They poses that they know everything and in reality they do not know anything. some random MBA guy takes the interview and would almost rag you. They will see your patience level but not the content you have. They will ask you to introduce yourself and then projects and asks you what are the reasons for hiring you. Does not he know why the hell he is hiring?
They say that there is no pressure and assure you that you are going to be an employee and once you join they will treat you as their servants. Believe me, no one has time to write this long interview experiance.
