1. Be prepared
Consult the company's website and ring for a brochure, job description and even the latest press releases, if needs be. If possible ring the contact person and ask if you can come and visit the workplace to get a "feel" for the job. Show positive interest in the work itself and be friendly to the staff if you are shown around. Most employers equate no knowledge of their company with no interest in it. Also, the more prepared you are, the less nervous you will be and the better you will be able to sell yourself. Remember that the contact person may be the person doing the interview - if you meet with them and establish a friendly relationship both you and the interviewee will be more comfortable when it comes to a formal interview. Many interviewers make up their minds about candidates in the first five or ten minutes, so you need to get yourself across quickly and clearly.
Arrive early - 15 minutes shows you are keen and reliable and gives you time to rehearse your key messages in your mind. Go in to the interview thinking of what you have achieved and what you have to offer. This will help vanquish the negative thoughts brought on by nervousness.
2. Look the part
Always dress smartly and appropriately for the post you are applying for. Making a first impression is important, and good grooming shows you have self-respect and know how to present yourself. Check your appearance before arriving for the interview - it's hard for the interviewer to concentrate on what you have to say if you have jewellery or hairstyles which attract too much attention. He/she needs to focus on you and your responses to questions.
Leave any clutter - coat, umbrella and rucksack - in reception, so you won't appear flustered and will have your hands free to offer the interviewer a handshake. It should be firm and friendly.
Remember to hold and folders etc in your left hand as most people shake hands with the right hand. Don't be caught having to awkwardly swap your folder or bag to the left hand when offered a handshake. Customs vary so don't be surprised if a female interviewer offers to shake hands when you are not expecting it or this is not a local custom. Accept the handshake as normal even if it is not your custom.
If you need to take material into the interview with you have it well organised in a folder so that you can present it without fumbling or rearranging loose sheets.
