Part of marketing yourself is effective presentation; looking the part, promoting a professional manner, positive body-language and your overall demeanour. If you look the part, and can demonstrate your experience and skills, you are well on your way to ensuring you are selected for the position.

Classic clothing is generally best for men and women. This usually means a suit with shirt and tie for men, and a business suit in a conservative style and colour for women.

Tailor your choice to the industry and the position for which you are applying. Find out what to wear as part of your pre-interview research about the company. Be clean and neat - shirts and blouses should be pressed and shoes polished.

Fashion statements or quirky accessories are best avoided when attending interviews - your interviewer will be expecting you to make an effort to impress and you cannot predict their interpretation of your unusual tie or funky shoes.

For women, make-up is an important part of image and grooming. As with clothing, it is important to note that different people will interpret different looks in different ways. For this reason, classic and understated day-time make-up is most appropriate.

Perfume and cologne should not be too overpowering.

Your interviewer will be considering you as a member of the organisational team, as an employee, and as a representative of the company to the outside world. You have to prove that you can perform well in a formal business setting, that you are a good communicator and that you will fit in with the office team. This can be a challenge when nervous, but a good interviewer will ask a mix of personal and work-related questions that should allow you to relax and be yourself, as well as discuss your candidacy in a professional manner. It is also important to remember that the interviewer is not the only person you need to impress. If you get the job you will become part of the team, so be polite and professional with everyone you encounter before and after your interview, whether it is the receptionist or the interviewer's assistant.

Be aware of your body language and what it communicates. Despite interview nerves, try to refrain from fidgeting, sit up straight, and maintain eye contact with the interviewer - this will express your interest. Take your time and consider what you are going to say rather than rushing into unprepared and possibly irrelevant speech. Try not to use slang phrases such as, 'you know' or 'sort of'. Finally, remember to smile and be yourself - it is important to you that the job and organisation suit you, so there is no point acting like somebody else in your interview.
