Samsung Research America Signal Processing & Algorithms Engineer interview questions

The process took more than a month. The recruiter emailed me regarding the position and scheduled a telephonic interview. The interviewer called me 10 min late and started asking throwing questions without even waiting for my answers. I could barely hear him and he asked me questions irrelevant of the job description. At the end, when I am asking the questions related to the position, he said he is running out of the time and cut the call.
