it’s our personal impression that you will not fit into our existing design team. Additionally we missed important personal properties. In our team everyone enigneer has to rely on each other team member. Personally I would not rely on the results of your statements or work.
Ouch. That's rather telling, because it's unusual for you to get such negative responses - they normally don't like to give negative feedback.
Why don't you try and do some practice interviews and get feedback?
Also, calling people stupid isn't a great approach. An interview is as much about making the interviewer happy as it is about actually showing how good you are. Many interviewers like to feel good about how great an interviewer they are, how smart their silly questions are, etc.
