The interview was challenging, it was not your everyday same interview with 1v1 interviewer. My interview consisted of a panel of 4 interviewers interviewing me. The inteview itself was roughly 2hours. Before the actual interview commenced, I had to deliver a 20minute presentation with no powerpoint/notes. Yes I just freestyled. It was a notch harder than IBM's but if you passed IBM's interview this should not be a problem for you yes I also passed IBM's placement interview.
The interview was all about showinh your character, personality and more importantly what you can offer. It is a two way process where you learn as much as giving it back.
Remember do not be shy to name few Oracle's competitors, i.e IBM, Microsoft etc.
Along with being honest and saying they are still a notch behind Microsoft. However, there long term goal is to eclipse Microsoft.
My panel consisted of 4, where they all took turn in asking questions along with one member grilling your CV.
I got a offer the following day!
