Why do you want to work here?
What benefits can you bring to the company?
What do you see as your main responsabilites here? (in other words,they want to know,do you understand what type of job your going for.Silly I know,but there it is).
What are your previous experiances,in relation to the job your applying for?
How did you get to hear about the job?
What sort of salary scale are you looking for?
Can you supply at least two references?
Dont get family members to make this up,please,as they will want direct contact with previous employers.They may even ask for a third reference,from a charactor witness.Someone who knows you (not a family member),but someone you have not worked for.
Just be yourself,plan ahead,what could they ask,do I know a liitle bit about the company.Sit comfortable at the interview.Try not to fidget,and above all,when answering questions,dont look at the floor,or the ceiling

Make sure you give eye contact as much as possible.Finally,show interest,and just enjoy yourself.If they want you,they will say so.If you dont get the job,it's valuable experiance,at a genuine job interview.Good luck.
