Don't forget your body language like making eye contact, your posture, not fidgeting and not mumbling.
Do not merely read through your CV. An interview is an opportunity to present all of the skills you have that your CV can not communicate.
Say thank you to your interviewer at the end and after by email or send a 'thank you' letter by post.
Don't stress yourself by thinking about negative thoughts.
Advice for Job-hunters:
"Develop all the info that you will need in filling out a job application in advance. Even if you are supplying a CV, it is possible that you will also need to complete a standard application for the human resources department."
