I applied through a recruiter. The process took 3 months. I interviewed at Oracle (Hyderābād) in Apr 2017
Interview
Asked about data structures and algorithms and few math problems. But taking more than 2 months to release offer letter(Still i didn't get offer letter). My suggestion is even if you got selected in oracle try other companies too because you don't know whether these guys give you offer letter or not. They are taking too much time and won't reply to your calls or mail. So don't waste your time.
decent amount of DSA and System design were asked, and behavioral questions. so prepare leetcode level questions and good amount knowledge in sql, java and also mostly oracle sql. overall it was good
First online assessment. Then 2 interview rounds + 1 hr round. This was during campus placement. In interviews they mainly asked about dsa, os concepts, logical questions and some system design questions also.
I applied through other source. I interviewed at Oracle (Seattle, WA)
Interview
i got a return offer from internship, and I had to do one additional technical interview because I was switching branch. He first asked me a OOP question, and then leetcode medium level question.
