Oracle Software Developer interview questions

I was selected from the campus. There were 3 technical and 1 HR rounds. First was written then 2 rounds of technical interview. Questions were mainly on data structure. Wanted to check the problem solving approach. Each interview was of 30 -35 minutes taken by different panels. Last round was HR where basic HR questions were asked

Typical interview process, HR reaches out followed by Hiring Manager's round. I had 8 rounds of Interview, all 8 people asked the same set of questions in same order. After 8th round, I told that I cannot come for further rounds. The HR understood that they might loose me and finally made the offer.
