There were two rounds. First round was taken by two interviewer. Questions were really good and interesting. 2nd round was taken by a manager. He was extremely rude. He was not prepared to take the interview simply googled for questions. Then asked to write two simple code which was very easy and third code was a bit complex and he couldn't understand my solution. Later he started making rude remarks like I am wasting his precious time with my attitude. Even if I am smart I might reject work. He talked very unprofessionally. Never expected such an experience from Oracle. Was very disappointed
