Be time have resumes
Dress well. Don't put on too much cologne/perfume/body spray. If you wear makeup, keep it natural! If you have long put it up nicely in a bun or ponytail. Be friendly, have fun with it like any other interview. It is mostly customer service so they want someone who is friendly. Don't forget to ask questions too! Always, in every interview you go to, have at least 3 questions to ask!
Look presentable, look the interviewer in the eyes when taking, answer honestly, show your friendliness side, do not give an attitude when answering, be polite .
Personal Interview focus on the Question and be confident.
Just answer the questions, be honest, dress well, and get ready for a fun experience.
