Datatron UI/User Experience Designer interview questions

This was the worst interview I have ever had. The phone screening went well, I had a positive experience. However, when I had the second round design interview, the interviewer was extremely rude to me. First off, he did not ask me a single interview question about my qualifications or past experience, instead he went through my portfolio site for what seemed like the first time ever. I asked if he wanted me to explain the projects, but he said no. He even said to my face that all my designs on my portfolio website were bad. Overall, this interviewer was extremely rude and unprofessional.
