Manufacturing Integration Technology Mechanical Design Engineer interview questions

The interviewer who interviewed me, 1) Doesn't even introduced himself, although it is another person who is supposed to interview me. 2) Used outdated materials for presentation. 3) Bad body language, who leaned against the chair (almost like want to fall down) with cross legs. 4) Cant even communicate properly in English. 5) He said he had 10 years + of experience in this line, dismantle a pen to ask design question and having difficulty to assemble back the pen after that.
