Easy, straight forward. The people who interviewed me were young people from certain departments who are not that specifically trained to perform interviews only. They just pretty much ask you questions from the sheets given by the company and write down your answers. They will not give you a hard time, that's for sure. They're not also looking for perfect answers, just be honest, say no if you don't know the answers to specific questions. They will like you if they think you can be a good team player.
