Oracle Internship interview questions

Week 1 - Applied for the internship and received a response within 2 days. Week 2 - Recruiter called me an asked me some basic questions about myself. (What I did in college, projects and all that). Two days later the hiring manager called me and asked me some more questions about myself and what tech trends I follow. Week 3 - Called me in for a F2F interview with the hiring manager and senior director. Asked me some basic technical questions. 3 hours after the interview ended, the recruiter called me and offered me the job and I took it.

Started with simple questions on data structures and algorithms. Bug-free codes were expected for almost all the questions. Most questions were on linked-list, stack, heaps, Binary search tree and self-balancing property. B-tree. Later an in-depth discussion of a project mentioned on my CV.
