The process is quite simple, depending on the team and position you are interviewing with. I met with three teams at Oracle HQ in Redwood Shores in a single day. I also had lunch with an alumnus of my school. The whole process was very smooth.

HRs were very nice, and the people who interviewed me were also very friendly. They didn't ask any challenging questions. We talked about my background and what their group does for most of the time, with some basic questions on Java, multithreading, and algorithms.

Some teams ask technical questions (Algorithms and Java), while others concentrate on behavioral and communication skills.

Algorithm question: Print the complete ancestral chain in a given n-Array tree. (You have to print all the parents till the root of each node of a given n-Array tree.)
