I applied through an employee referral. The process took 2 weeks. I interviewed at Uber (San Francisco, CA) in Nov 2015
Interview
After getting a referral from a friend I got as far as a very disappointing phone screening. The phone interview itself was with a very disinterested HR woman, who just read question off of her list, had no follow up questions and in general made me feel I was wasting my and hers time.
