Uber Manager, Strategy interview questions

8 stages interview - including case-study in the final round, which included excel and presentation. Overall enjoyed the process and very nice people, however extremely long. Got rejected in the final stage,

Internal recruiter was good - communicative and sent a lot of helpful details on the process, expectations, and interviewers. Was sent a take home case study to complete after the initial conversation with the hiring manager. I would estimate that I put in about 40 hours of work into the case study. Up until this point, my experience with the interview process was generally positive. However, despite the amount of time and effort I invested into the case study, I found the panel of 3 interviewers during the final round highly disengaged during my presentation. I could see from the get-go that some members of the interview panel were staring out the window as I was presenting and, when it came time to their Q&A on my case study, I was lobbed a couple of softball questions (that I not only had prepared responses for, but entire pages in the appendix that directly answered their questions). When it was turned over to me to ask them questions, they cut me short to end the video call. It was clear to me that they had already made up their minds on my candidacy before the interview began. Given the amount of time and effort put into the case study, it would have been nice if they at least pretended to engage with me as I was presenting and gauge if there is anything here that might change minds. If the team had already made up their minds about my candidacy and my case interview wasn't going to change their minds, I'd have preferred if they had just cancelled the interview - it seems an immense professional discourtesy to waste an hour of 4 people's time just to 'go through the motions' on an interview process. I received feedback on my case study not being "detailed" enough, although I flatly reject that as valid feedback - if my case study was inadequately detailed, I shouldn't have been receiving softball questions that I could answer without pause.
