The key to a successful interview is plenty of preparation and research. Also revise and make sure you have a copy of your CV to take with you.
The interviewer will ask you to draw on your experiences to answer questions. So preparing possible answers will help you to articulate what you want to say and not babble.
This is a list of things you may be asked about:
• How your present and past experience relate to the position
• Your current and future career goals
• What skills and expertise you have to offer
• The skills that you would like to develop or improve
• Location, salary, and lifestyle priorities
• Kinds of people and environments you prefer
• Past experiences you want to highlight such as volunteer work, hobbies, travel

On Interview Day
Dress Professionally
Dress in line with the company you are going to be interviewed by. If in doubt, wear a suit. Visual impressions are very important and will influence the interviewer whether they are aware of it or not.
Arrival
Arrive early so you can get your bearings and arrive calm. DO NOT arrive late. Nothing destroys your chance at impressing an employer more than arriving late and offering no explanation. If you learn at the last minute that you are going to be arriving late at the interview, call and let the interviewer know.
First impressions
First impressions take thirty seconds to make.
Establishing rapport, direct and sustained eye contact, a firm handshake, a warm smile, good posture, and introducing yourself in a confident manner are important ingredients.
Body Language
Use good posture, and look the interviewer right in the eye. Sit up straight. Never slouch. Speak Clearly - Don't mumble
Listen Before Answering
Allow the employer to begin the interview, but be prepared with some opening statements or questions such as, "I understand that this position involves…," or "What are you looking for in a job candidate?"
Make sure you understand the question. If not, ask the interviewer to clarify it.
Previous Employers
Never, ever say anything negative about your present or previous employers. No matter how much you may have disliked someone, find a way to give your experiences a positive spin.
Thank the Interviewer
On leaving, thank the interviewer for taking the time to interview you.
Next Day
Send a thank you email. . Express your appreciation for the opportunity to be interviewed, re-confirm your interest, and re-emphasize how your background and skills are of interest to the company.
