Uber Developer interview questions

Uber has a very simple hiring process: Step 1) Technical Phone Interview Step 2) Interview in our SF office Step 3) Offer! I didn't understand the problem well during phone interview and spent 30 minutes coming up with a solution that wasn't doing the right thing. After communicating with interviewer, he was nice enough to go over time with me and I finally got it done. (The phone call lasted for 75 minutes) Recruiter got back to me quickly telling me that feedback was great. Then on-site interview was scheduled. There was a three-week gap between phone and onsite but I finally interviewed at SF. Everyone I met was nice and approachable. They patiently listened to me explaining my thinking process and provide feedback along the way. Two days after the interview I received phone call from HR telling me that they decide to extend an offer. Enjoyed the process.
