Fail to prepare, prepare to fail. The more homework you can do on the company, the more comfortable you will feel answering questions on the benefits you can bring to your new team. If you can also demonstrate knowledge of your potential new company during the course of the interview, the fact that you are willing to go that extra mile to succeed will become clear.

Dress smartly, act professionally (but not like a robot) and keep control of your body language. Do not fidget, and try to look calm and confident without seeming arrogant.

There is no harm in practising answers to certain questions which may come up. It ensures that you will not run out of things to say. Be wary of sounding as if you are merely reciting learned answers however. Typical questions could cover how you would describe yourself, what your plans are for the future, your strengths and weaknesses, your motivation and what you could bring to your new role. Do not dwell on any negatives unless it is to turn them into a positive - for example how you have recognised a weakness in your commercial makeup and have taken steps to eliminate that weakness.

An interview is a chance for you to ask questions too. If you don't understand something, don't be afraid to get clarification. It is also a good idea to prepare some questions of your own in advance to show you have a genuine interest in the role.
