Oracle Applications Engineer interview questions

Describing the campus placement procedure: It started with technical aptitude objective exam which was quite difficult as there were any questions from advanced algorithms and many other questions which tested knowledge rather than the understanding of subjects and I believe most of the people marked many answers randomly. Second and Third round were a Technical interview. Questions were fairly easy for me. Question consisted of basic Data Structure and Algorithm questions along with some puzzles. The Final round was an HR round which was only a formality.
