Uber

I have two coding questions that I attempted to solve, but I didn’t get the best or most efficient solution. I would like help, especially for four rounds of problems.

Uber's interview process was the most chaotic of the lot. First, I was set up with a completely wrong team for my interview. The interview itself went well. Some of the interviewers were clearly untrained and didn't really know what they were doing.

The first interview is mostly about coding. The first part is about CV, but not so deep. It takes 10 minutes. An easy if-for problem is followed by a mid-problem. Finally, 10 minutes are allocated to ask questions.
