I loved the experience of interviewing for Uber. It was my first technical interview and I was fortunate enough to get an offer. There were three 45 minute interviews, each with a different interviewer. Two interviews were technical, and one was a system design interview (still technical but not so much). The interview opportunity was in partnership with my school so I am not aware of what interviews are like typically. For the 2 technical interviews, we were required to code on out laptops. For the system design interview I wrote code/pseudocode on a whiteboard. The questions were a lot easier than what I was expecting. None of the questions stumped me. If I got stuck in the middle of writing an algorithm, I would just talk through what I was thinking and the interviewers would guide me through it.
