To be honest , I have a part time doing sales on a phone but its boring i sit there for 4 hour without a break on the phone repeating my self like a broken record. What i would like to do is be a receptionist or a administrator , where i am doing different things and different times in the day.

Some great advise posted already, so a few thoughts that might help from me.
Very first impression is important. A good one won't get you the job on its own but a bad one will loose you it.
If they think you cant be d to spend time on yourself then its unlikely they will believe you will spend time doing a job.
Clothes and hair style are largly unimportant unless absolutely outrageous, its the cleanliness of yourself and the clothes that matter.
Unclipped dirty fingure nails for example and clothes that look like you have slept in.

One helpful hint might be that if you concentrate on listening when being talked to it has the effect of:-
a) actually listening to whats being said
b) makes you look attentative and interested as your eyes automatically widen slightly
c) You remain looking directly at the interviewer.
d) if there is second person interviewing you switch your view and full attention to them when they speak.

Much could be made of the attribitues you bring to your current part time job -think positively and list them. Reliability, responsibility, working in a team, communicating with the public etc.
You've been happy working there but need to move on to something with a more varied challenge. Do not critise your current job in any way!
Questions you might expect are hobbies/interests : you need to expound a little on a couple to show you are not a couch potato : beware : I also have the T shirt Adey was talking about!

When asked for your questions, You would be expected to ask about pay and hours if not already known. For other questions the best are mundane ones that already presuppose that you are going to get the job. Any Dress code? Know of any night school/training courses that I could attend in my own time that would help?
Finally, and really impotant, stand up and say in your own words
"Thank you for giving me this interview...I'm really interested in what you have told me about the job and I would accept it if it was offered. I really hope you will consider me for it"

Good luck fella

Just what sort of job IS the lad applying for ?



<It's OK. I've just banned myself for the night>

It's hard these days

Think yourself lucky it still is

What is?

Have I had my tea yet?
