Oracle Senior Software Developer interview questions

Direct on-site without a phone screen. They had a recruitment event going on with multiple candidates and decided to do an on-site with 5 rounds. Overall process was ok. Recruiter was friendly and prompt with the result. One thing to note is the interviewers were some of the rudest ones I have ever experienced. They laughed when I made a small mistake with one of the programming exercises. Overall behavior of the interviewers was extremely rude. This was for the Oracle Cloud Security team. I know Oracle is a big company but with this kind of an attitude it reflects the kind of peers I would've had and that's not the way people want to be treated. I will never interview with Oracle again.
