I applied online. The process took 6 weeks. I interviewed at Oracle (Bucarest, ) in Nov 2023
Interview
There was an initial technical interview about Design Patterns.
Then followed 5 other interviews. Only one of the 5 was non technical, about what I would be working on, how they are organized in their team. The rest were about solving a math problem, an informatics problem, System Design in the Cloud and Merge Sort.
Each interview lasts for one hour.

I was not selected and kind of knew after the 3-4th round. But posting the kind of questions asked in the process if it helps
