Uber Software Engineer interview questions

Contacted by recruiter in July 2017 via email. Initial chat with recruiter went fine and had a technical phone interview via coderpad. Found the question simple but difficult to interact with the interviewer. Interviewer called in 20 min late, and had an accent. He said i spoke too fast, while at times i had a hard time understanding him. He wouldnt wait for me to complete the implementation and interrupt often with questions on corner cases. I would be personally preferred that he wait till I finished a sentence! Completed only about 75% of coding. As expected, didnt get a callback for a followup interview
