Extreme Networks Senior Linux Software Development Engineer interview questions

After a phone call with HR, video round technical interview was scheduled. In that round the interviewer was in a hurry to finish his all questions. He did not bother to look into the CV or the work experience. He just started asking question from what he had prepared from his experience and expertise. If the CV was selected for an interview then definitely there was a match and the interviewee expects question from his/her work done area. So the overall experience was very bad. I was asked shell script, routings, DNS and other networking questions which all are not part of my work experience or not even mentioned in the CV at all so it was kinda boring.
