Uber Software Engineer interview questions

I applied after fihgting against the UberBot. They asked for my score then I had 3 interviews. The first one was a normal one about my cv and some school projects. The second was about the same things as the first but into deeper technical issues (such as some algorithms complexity, datastructures used...), the some general computing knowledge questions (it was these ones I found difficult, about computer's memory and others stuff) . And finally the coding interview wasn't that hard, it was a "kind of" branch&bound algorithm.

Was Contacted After Completing HackerRank Challenge. Received phone screen with code pair. Then was flow out to San Francisco for onsite interviews. Interviews with 5 pairs of Software Engineers. Asked me to code on my laptop for one Interview. The rest were white boarding and system design questions.
