Uber Software Engineer interview questions

I had a recruiter reach out to me expressing interest in having me meet with the team. I did a phone screen with the hiring manager, a coding exercise, and then had a full day of on-site interviews. The hiring manager was very nice and enjoyable to speak with, however, the rest of the team was pretty awful. Folks would smirk when they didn't like your answer or thought they had "gotten your goat" so to speak. Another time I had an interviewer completely disinterested and checking his phone for minutes at a time while I was answering his questions. A lot of the folks hadn't looked at my resume before speaking with me and didn't have a copy when speaking with me. I've interviewed at quite a few companies over the course of my career and Uber is far and away the most unprofessional and worst experience I've had. You can sense they are growing quickly and potentially hiring bodies more than quality candidates. To add insult to injury, the Uber driver that brought me to the interview talked about how terrible Uber had gotten over the course of the few years he'd been a driver for them and somewhat eerily we passed under a sign on the freeway announcing an upcoming protest at the Uber office. Yikes!

Contacted the recruiter and soon got a phone call from the company. After 3 phone screens in the less than 10 days, I was scheduled for an onsite. They agreed to reimburse for the costs but since the interview they have been mute. The onsite interview was supposed to be with 5 people, but it was cut short to only 4. The excuse was that the final interviewer had something emergent came up. In hindsight it seems they already decided not to hire, even though I thought I did relatively well. Most of the interviewer seems very professional, except one, whose body language and facial expression was saying that I was wasting her time. The recruiter was silent after the interview until I pinged her for an update. She told me that I was not a fit because the team was looking for a very specific candidate. In hindsight, the statement from the recruiter and from some other reviewers cannot be more true: the company is looking for VERY SPECIFIC skill set and is not looking for anything remotely like a generalist. The position I applied for was in mapping and logistics and they seem to expect me to know all the algorithms in computational geometry. My friends who were hired by a different team in the company was hired because he knew exactly what the team was looking for. It looks like people were hired to solve problems that already have and not the ones that will come up in the future. In other words, the company's hiring demeanor is very short sighted.
