Uber Senior Software Engineer interview questions

The process with the recruiter was very smooth (no call, only email). Tech screening - the worst experience I have had to date - I asked clarifying questions on the input. The interviewer (probably unintentionally) misled me. Thus I had a different algorithm than what was needed. - Sample inputs were bad and unclear on input format. This added to the wrong clarification from the previous point (the same input would apply to multiple questions, likely interviewer got this from a different question). - Interviewer was in his kitchen with video on (totally fine). But another person frequented the video and peered into the screen often. They has side conversations with the other person, with the mic on. Very distracting to know if they were talking to me - I implemented the solution for my understanding of the question, and discussed its complexity. Only then did he say that my understanding was different from what he wanted - 15 min left., I am trying to implement the new aldo, and the interviewer insists that I use a particular data structure ONLY - Interviewer did not know what a "post-increment operator" is!!
