Uber Senior Strategy and Operations Manager interview questions

1st round - Recruiter screen, 30 minute phone call - great conversation with some jokes about my current employer (a competitor to one of their lines of business) that were borderline unprofessional but I am pretty laid back and appreciated the banter. 2nd round - Analytics test - lots of pivot tables so brush up on those and the Uber terminology, you can find online if they dont give you that info up front. 3rd round - Spoke with someone else in the role in a different market, great conversation - turned out I was doing a lot of things in my current role that they are looking for the new hire to do so everything flowed very well. 4th round - Case study, basically told me about a new project they were considering testing out to help with operational efficiency. Asked for 8-10 slides to talk about strategy and operationalizing a pilot program rollout, along with how to track success, etc. Took about 15 hours of work but I'm a bit of a perfectionist on powerpoint. 5th Round - Onsite marathon day, Uber flew me out to SF to meet with about 8 people total. 3 'rounds' were in person interviews, some 1:1 and some panels. 2 more rounds via webchat with managers in other regional offices. Thought everything went really well overall and was really excited when my final interviewer told the recruiter that she would walk me out herself, and reconfirmed my comp requirements as well as soonest possible start date. Followed up with the recruiter afterwards and was told I'd hear back very soon. This is when things went south - did not hear back from the recruiter for about 2 weeks at this point. Tried emailing and calling to no avail. Finally reached out to the employee I spoke to in Round 3 via LinkedIn to ask if something fell through the cracks or if the recruiter had left the company - they must have notified her because the next morning I woke up to an email telling me that I was rejected. Was super disappointed as I really wanted to join the team, and more disappointed that I didn't get any valuable feedback that I could have used to learn from.
