Applied online 2-3 months before. The HR interview gained me a hiring manager interview. The job supposed to develop independent Oracle partners to engage close and implement projects based on an Oracle set of SaaS solutions. After 2 weeks of waiting for progress, I found out that they added a mandatory requirement - advanced Russian language. Wrote 2 angry notes to HR and to the hiring manager and withdrew from the process

3 Rounds. First round with recruiter, then manager, and then team. Main round was with the team to present yourself and why you want to work at Oracle. Pretty straight forward interview process in that sense.
