I want to work in Adinik's shop. This is the first interview in my life, so I'm a little uncertain about what to prepare and how to do it.

It depends on what position you are applying for. Think about what this position needs to do, such as shopping guide. Be bold and don't be shy, or you won't even dare to shout a welcome. In addition, speak louder and speak slowly. Take it easy. Actually, it's nothing. It's just an interview Don't worry. No big deal. Just pretend to chat with people.
