Oracle Appplication Engineer interview questions

I had multiple rounds of interview, including a panel interview. Skills tested were IQ based, concepts based on OOPS, data structure questions, algo based and problems with space and time complexity

I was only in the first round. The interviewer covered questions related to my project, some questions on data structure and algorithms. Also asked 2 quiz question. The interviewers were very responsive and liked to know that what we think during solving questions.
