I applied online. The process took 2 weeks. I interviewed at Uber (London, England) in Feb 2015
Interview
The first stage of the interview process is a phone interview. You are to book time in the recruiter's calendar online which incidentally is very busy so that's probably a good measure of how much Uber is growing/how competitive it is for each role).
The call process should not be underestimated. [From my experience] They will ask why you're attracted to Uber, then test your knowledge of the platform and see how you're able to think about the challenges facing its growth. Make sure you are familiar with all the Uber jargon so that you sound the part at the very least.

Interview questions [1]
Question 1
they will deep dive into your experiences, also how frequent you use those data tools
Five to seven rounds of interviews, tests and presentations just to get a “no, thank you” at the end without much of a feedback. Acceptable for regular recruitment but not after weeks dedicated to the process.
Pretty easy at early stages - just need to know about supply and demand basics. Analytics test is harder, but manageable if you know Excel well. They are definitely interested in your problem solving abilities and ability to "get things done" with minimal supervision.
