Uber Software Engineer interview questions

Telephonic interview, Interviewer seemed to be very hostile, disrespectful, rude and very bad attitude. His only motive seemed to be prove you wrong and worthless. He seemed to be obsessed with nosql and already passed judgement that world has moved from sql to nosql. Almost all essential services are still running in transactional world so passing this kind of judgement is too pre mature.

Typical phone screen interview last around 45 min, spend the first 15 min chatting on the background, then a very simple coding question. Find the lowest common ancestor in a binary search tree. Then the last 15 min talking about the company culture. After that I receive an email that I was rejected.
