Uber Software Engineer interview questions

It was a crappy interview process... I had my interviews scheduled and the interviewer from Uber never bothered to Skype call during the interview time. This happened several times with my time wasted repeatedly. Recruiting team takes too long to respond to anything informed to them like they are too busy or something. After wasting my time with repeating interview rescheduling and interviews not showing up.. I give up and never plan to apply to Uber. Uber employees behavior is highly disrespectful to the interviewing candidates and very unprofessional which I did not expect for a company that well funded. But speaking to them many of whom refused invitations to interview with Uber, Uber interview process seems to be crappy for everyone.
