Vecna Robotics Robotics Software Engineer interview questions

mostly questions regarding projects listed in resume. Some follow up questions relating to processing and interpreting the Lidar scan data, as well as autonomous mobile robot motion planning, navigation and localization questions

There was a C++ assessment before, which I cleared. I got a phone interview. The interviewer was very rude and was frankly not that interested in taking the interview. I was not given a chance to ask any questions regarding the role or company. When I asked, whether if possible, I can ask a couple of questions that I had, he said sure at first. Then when I asked a question, which was quite elaborate, he just cut the phone call, while I was finishing with my question and I got a generic reject via email in an hour. That is the absolute worst behaviour I have even encountered in an interview. To the hiring team, please don't waste time of the candidates. The job searching is already very stressful process, so atleast avoid the rude behaviour.
