Oracle Senior Software Engineer interview questions

I connected with a recruiter, had an initial phone screen and was asked to come onsite. During onsite there were 4 rounds along with a lunch interview. 2- Coding 1- System Design 2- Behavioural Lack of practice from my side. The coding rounds had questions straight out of leetcode and geeksforgeeks. Interviewers themselves did not have a complete understanding, rather was expecting the exact same approach that they saw online. I found them intimidating, it was more of an interrogation and less of a conversation which made me uncomfortable and from that point it went downhill.
