Uber Engineer interview questions

Awful Interview Experience. I was referred by a former coworker. I got through the initial phone screen with the manager and an employee. On the day of the in-person interview, the second interviewer asked me questions that he did not know the answers to. It was very awkward and unprofessional. After four hours of interview I did not get to meet the hiring manager even though he was originally on the schedule. If this is an indicative of how Uber treats its potential employees then it does not seem like a good place to work. I accepted a job offer from an even bigger and reputable company the next week.
