Oracle Director interview questions

The whole process took just over 3 weeks. I was contacted for a role I applied for on the website. I spoke with a recruiter who scheduled a call with the hiring manager the next day. I then spoke to a pair of peer-level members of the team a couple days later. Up to this point, everything was very typical. After that, I was scheduled for a panel interview where I was to meet 7 members of the team I would be managing. This was extremely strange to me as I've never heard of anyone interviewing their potential manager. Additionally, I was asked to present a case study, but was given no information on what to present other than to 'talk about some of the things you've done'. I was told that the panel would be casual, and a 'they get to know you. you get to know them.' kind of thing with me presenting on my case studies followed by questions. I spent a week putting together 2 case studies to talk through. When the call started, they immediately told me to 'give my schpiel' without asking any questions. I presented over zoom for nearly 40 minutes, trying to engage the group, and asking for questions along the way, which they declined. I got to the end of my presentation and asked again for questions. They asked 2, which I answered. Then they asked me to leave, so they could ‘talk about me’. I followed up for feedback, but did not hear back until they asked to schedule another interview with the hiring manager’s manager a week later. I assumed it went well, but over a week after that last round, I have reached out twice to the recruiting team for feedback and to check in, and have been completely ghosted. I guess they found someone else. Personally I feel insulted at the lack of respect for someone whose last round had them speaking to an SVP.
