Uber Software Engineer interview questions

Totally chaotic and unresponsive on HR part. Firstly, they didn't schedule the interview until I call them up for an update. I lost count of how many times I called them. Then the interview got postponed twice as the interviewer does not show up at the scheduled time. Finally after so much hassle, I got to give the interview but they don't have the basic courtesy to respond back with the status(It has been over a month). Normally, I would have assumed that I didn't get through but with this level of irresponsibility, they might have never taken feedback from interviewer as well! The only bright side is that I enjoyed the questions in the interview. Probably one of the elaborate interview at screening level. Unfortunately, I can't recollect the exact questions as it has been more than a month. Will update the post if and when I remember.
