Trusscore R D Material Scientist interview questions

They did some introductions and I introduced myself. They did a presentation on the company. They asked me technical chemistry questions (related to polymers, solubility, procedure of film-making). Finally they asked me if I had any questions. The guy asking the technical questions was a little rude and demeaning, and made it seem like all the questions he was asking was common sense. All of their co-op students in the interview meeting were in their last study year, while I was only in my second.
