Uber Developer interview questions

I was contacted by HR on phone and was setup a phone screen. It was supposed to be a Skype interview, however, the interviewer ended up calling on phone. He was 15 minutes late. It was pretty hard to understand the accent as well.

The process started when I received an email from a recruiter. It was followed with a quick phone call to discuss my background and the position at Uber. We set up a phone screen shortly after. Admittedly, I did not do very well on what should have been a simple problem, so I was not expecting to move forward. However, I never heard from Uber again after the phone screen. I think giving a candidate a formal rejection is the least they could do.
