Oracle Senior Software Developer interview questions

Two steps : First HR call and discuss about the role and then onsite interview where first meeting with senior members in team for technical question and then interview with manager.

I got a call after applying in Linkedin, Very unorganized process First round is formal HR round. Second round was postponed for 3 times and recruiter asked for my interview timings and scheduled interview in exactly opposite time. Interviewer didn't even ask for my details and literally grilled me on CS background for whole 1 hour
