Uber Software Developer interview questions

There is no much to say about this phone interview. It seems the interviewer just followed a list and asked me questions on it. I am not an English native speaker, and I said pardon too many times in the interview, I guess that made him lose patience and want to end earlier.

Scheduled 30 minute phone interview by email which was very timely. A man walked me through a few categories of questions meant to more specifically define my strengths and weaknesses. The interviewer stressed that this was not necessarily to filter out candidates but group them according to like qualities for further filtering later. Categories included C++, OpenGL, Datastructures, and Networking. Afterwards the interviewer answered a few questions I had about future interview processes, but I did not want to keep him on the line too long as I imagine he tries to stick to 30 min bursts. He was very polite and positive, and clearly knew what he was talking about, which is a first in my experience with interviews involving technical skills.
