I completed 3 stages
1. phone screen with HR - very straightforward, asked about previous work experience and why you want to work for Uber and what makes you a great candidate
2. Analytics quiz - not super difficult but I would recommend preparing, get familiar with the lingo and see if you can find some examples online
3. video interview with person you would be reporting to - fairly casual, asked about interests and previous work experience. Also asked 3/4 short case questions. Be prepared to talk about the UberEats business model. Know what some of the challenges are and be prepared to discuss them.
I didn't advance to the onsite interview.
