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.
