Uber has a very simple hiring process:

• Technical Phone Interview
• Interview in our SF office
• Offer!

I didn't understand the problem well during the phone interview and spent 30 minutes coming up with a solution that wasn't doing the right thing. After communicating with the interviewer, he was nice enough to go over time with me, and I finally got it done. The phone call lasted for 75 minutes.

Recruiters got back to me quickly, telling me that feedback was great. Then the on-site interview was scheduled. There was a three-week gap between the phone and on-site interviews, but I finally interviewed in SF.

Everyone I met was nice and approachable. They patiently listened to me explaining my thinking process and provided feedback along the way.

Two days after the interview, I received a phone call from HR telling me that they decided to extend an offer. I enjoyed the process.
