Things to do on an interview.

• Fold your hands in front of you when seated.
• Be confident, smile.
• Tell them why you think you're best for the position, hard working, honest etc..
• Ask one to two questions at the end of the interview, they'll probably ask if you have any questions.
           ○Some good questions include, "What's it like to work here?", "What is the company about", "What is the salary", "When will I know if I have obtained the position or not?".
• Also, a thank you card is a good idea. Either give them it at the end of the interview, or send it in the mail as soon as possible. This shows that you really cared about the interview, and that you liked the company and it's surroundings.
• It's good to have a references sheet, hand them this at the end of the interview.
