Oracle Application-Engineer interview questions

Got interview call from referral. The interview was pretty standard based on data structures that got progressively harder over the next 3 interviews. Initial rounds focused on linked list and arrays but latter focused on designing backend system including database and UI(on paper and discussing)

Three face to face rounds. First round will have some basic core java questions and basic programming. Second round consists of intense programming and some implementation questions. Third round is managerial with questions regarding your work and experience.
