What do i answer during a job interview when they ask, "why do you wanna work here?" and other questions?

As for why do you want to work here, do some research about the company before you go. It's almost guaranteed you'll find something you like. Say something like, "I've always liked pumas, and when I did some research about the company, I found out that it would really help me find out more about shoe production from the ground up." Some crap like that. When they ask why they should hire you, just outline your best qualities and relate them to the business. For example, I'm really organized, and in a large company, you have to be organized just to make sure everything gets where it's supposed to go... relate it to your own skills. Good luck!
