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

Straight forward interview process. Applied on day 1, phone screen on day 4, behavioral w/ PM on day 6, two technicals with principal developers on day 8, received verbal offer on day 10. All interviewers were kind and knowledgeable.
