Don't just reel off facts about the business, inject some personality and be outgoing, that will carry you a lot further at hobbycraft than previous experience
Listen and understand what the manager wants you to do and achieve. Dress appropriately. Practice communication before the interview. Don't be cocky, use the appropriate language. Speak with pride. Always ask questions that your are unfamiliar with.
Just try to be confident even if deep down your nervous, keep talking sell yourself in a way to the employer talk good employers like to see your personality.
Just try to think of it as a normal day or like your talking to a friend. This is what I do at interviews and even though I talk and giggle alot out of abit of shyness I do try to show confidence but friendliness at the same time. It's all about talking a good show and interviewers like it every interview iv ever had iv passed accept for the odd one when I was quiet and had a brain freeze.
