Buopso interview questions

I gave an interview in this company. I want to say that interviewer has no manners and knowledge. First he said why you have a resume of five pages, ?? I thinks he never seen a resume of an experienced developer (4yrs). Second things he gave me a coding task and at the same time he just started asking theoretical questions while i was doing coding task. And he said answer to questions and do the task on the same time. I think he was taking an interview for the first time in his life but it should be common sense that you cannot think about coding tasks and answer theoretical questions at the same time
