Uber Senior Android Engineer interview questions

The first round went well you have to create an Android app in 40 mins after completion of that round is DS algo. Guys who took 2nd round were super dumb and were not able to accept solution other than what they have recited. Also they keep on disturbing you continuously, even when you ask for a certain time, worst interview experience I ever had maybe Uber should look at their hiring process. HR is also not very communicative they don't even have valid feedback to give.
