NETSCOUT interview questions in Colorado Springs

In person interview with hiring manager. The questions mostly pertained to gauging personality. An "optional" take home skills test was offered. The manager reviewed the results and explained how nobody on his team did as poorly, not even himself. The response was spiteful when a simple rejection would've sufficed. One question was about something that really got me jazzed or excited and the interviewer proceeded to tell me about another applicants answer and how shallow he felt it was. I received the interview through a recruiter wo had me take a skills assessment. Just before the interview was over the manager asked about my score, which is completely understandable. But then he pulled out a similar assessment he'd taken, compared it to his own and questioned why I did worse then he did. If I didn't meet the initial criteria why even bother with an interview? A very unprofessional experience.
