First step: Phone screen.
Second step: Exercise.
Third step: Technical phone interview.
Forth step: Onsite.
Everyone was friendly and helpful. Questions were challenging yet well designed. Recruiters were professional and efficient. I very much liked the process. The more you know about Uber the better you can answer non-technical questions.
I applied through an employee referral. The process took 1 week. I interviewed at Uber
Interview
I was referred by a friend and set up with a phone screen with the technical recruiter within a few days of the referral. It was a brief fifteen-minute conversation, and the recruiter scheduled a tech screen with an engineer afterwards.
During this tech screen, the interviewer asked me to solve one coding challenge through a pair programming module. I completed it, then made sure to solve for edge cases, and then asked some questions at the end.
My interviewer seemed rushed for time, since he ended the conversation right on time and left with an abrupt "goodbye!".
I received a rejection within 48 hours, but knew exactly what I messed up on and definitely can't blame the interviewer -- he was very helpful in delivering feedback at the end of the interview.
I applied online. The process took 3 weeks. I interviewed at Uber (San Francisco, CA) in Jun 2015
Interview
Meet with software engineers. They asked me coding and design questions. I felt they mostly cared about design and not that much about code.
At the end I met with a manager who asked me about my previous work.
I had lunch in their offices about halfway during the interview. Lunch was good.
