Oracle Software Developer interview questions

Spoke with the Manager, Architect and one of their senior engineers, they got me through the code and asked me about reactive and completable futures. Also had some calls with HR before hand.

Multiple rounds of 1 hr online coding interviews with emphasis on time complexity and data structures I code mainly in C++ and while it's allowed some interviewers had a difficult time catching up had more explaining to do. Ideally be prepared to do it in Java as that is the main language the company uses and some questions are strictly Java related. Total number of rounds was 4 but I refused the last one. Overall very time consuming process.
