If you've worked other places, print out the addresses and phone numbers, along with your boss's names and all of that stuff. They might want that information. I'd bring in a cover letter and a copy of your resume to give to them too. Make sure you get there early and dress nice, and all that. good luck!

Be yourself. try not to show your nervs, be friendly,

It would help to know what field, but if this company has a website, be sure to visit it. Learn about the company and try to kind of mention something so they know you took the time to look--but be smooth about it, you know?

Dress neatly, look the interviewer in the eye and shake hands. Don't give one-word answers, but also be careful about going on too long. They will probably ask if you have any questions for them. It's good to have one ready, but make sure it's not something like "How much time off do I get?" You could ask about opportunities for advancement; this will show that you're ambitious and are interested in staying with them for a while.

Good luck!

Edit: Lizzy's right. Be sure to have a copy of your resume and contact information for your references. Honestly, I was interviewing for a teaching job, and there were several other people there. They gave us applications to fill out, and I couldn't believe how many of these people--and they were not young--did not have the addresses and phone numbers with them for their references. I was annoyed that the secretary saw that and not the person doing the interview, because I thought it gave a very bad impression.

Yes There are many

1. Make sure you don't get nervous there.

2. Prepare with a mock session with you friend.

3. Try to make a good body language as it is the most important thing in interview.

4. In interview your voice should be steady and clear and also your confidence is what interviewer will look for.

5. Wear a formal and comfortable dress in interview.
