I applied through other source. The process took 3 weeks. I interviewed at Uber (Washington, DC) in May 2014
Interview
Spoke to an internal recruiter and then to team lead on the phone. Was then asked to do a written assignment. I had 24 hours to research and review a prompt for a particular city and write up a plan to change regulations there. Then I was brought in for 2 in person interviews and was called later with a job offer.
