Uber Software Engineer interview questions

I was contacted by the recruiter via phone to access my interests in Uber and why I wanted to leave my current job. I was given the choice to either do a phone screening technical interview or go on-site for an hour since I was a local to the area, in which I chose to go onsite. After passing the preliminary screening, I was invited for the full on-site interview. Since I was interviewing for the Map Store team, I was told beforehand to focus more on graphs, trees, arrays, and linked lists. The questions were fairly hard/tricky to come up with a solution in the time frame that you were given and there was the expectation that you would write your code in CodePair after whiteboarding your solution, which I was not able to do for two of the interviews. However, the interviewers were very nice and helped me through a lot of the parts of the problem where I got stuck, so I had a somewhat complete whiteboarded solution for all the interviews. I struggled a lot through the system design interview due to my lack of experience with distributed systems, but the interviewer took that into account. While I did not pass the interview, the recruiter and interviewers that I have met are some of the nicest people in tech that I have had the pleasure of talking to and seemed extremely passionate about their work, and my experience interviewing for the Colorado office has been nothing but positive.
