Bossa Nova Robotics Computer Scientist interview questions

Received an email shortly after applying to schedule an initial phone screening which included background questions and basic coding. After phone screening, never heard back again. During the phone screening, it became clear I was not a good fit for this position. That would normally not be a problem - that is the point of the phone screen after all - but the interviewer was incredibly rude throughout. He repeatedly interrupted me while trying to explain my answers, never gave me an opportunity to ask any questions, and didn't have the courtesy to send an email saying they would not proceed with my application.
