Oracle Software Developer interview questions

I applied for college grad role. Interview was straightforward: 1st round OA (2 easy-medium leetcode) and 2nd round you talked to 3 engineers who asked you some conceptual questions, past experience, and a coding question (easy to medium).

8 interviews : All technical interviews asking medium level leetcode and projects. I dont know why they took 8 interviews, it was a really unprofessional experience interviewing oracle. Would not want to work for that organization, after taking 8 interviews all of the same difficulty level and leet code questions , and reaching the final round they rejected because i didnt have enough experience.
