Oracle Project Intern interview questions

It was a 1-day interview process consisting of 2 rounds. The first was a technical round, followed by a combined technical + HR round. In both rounds, my projects were discussed in detail, with the interviewers asking in-depth questions about the architecture, implementation, and challenges faced. The overall difficulty level of the interview could be rated as easy to medium.

Interviewer was nice he asked me questions based upon DSA and some CS Fundamentals including operating systems. like deadlock memory management. They also asked me questions from my projects and pors. in dsa they asked me trees and priority queue and min and max heap
