Do Your Research
Virtually all jobs involve a face-to-face interview, so do your homework about your potential new employer beforehand! Try to anticipate likely questions - and look at the company's website to find out all you can about them. This will give you an edge in understanding and addressing the company's needs. The more you know about the company and what it stands for, the better chance you have of selling yourself. You also should try to find out about the company's culture to gain an insight into your potential happiness in the role.

Look Sharp
First impressions are vitally important, especially your appearance. A couple of days before the interview select your outfit. Depending on the industry and position, your smartest suit is usually the best option. Even if the company operates a casual policy, at this stage it is important that you are looking your very best. Above all, dress with confidence. If you feel good, others will respond to you accordingly.

Be on Time
Never arrive late to an interview. Allow extra time to arrive early in the vicinity of the building, allowing for factors like getting lost. Arrive 15 minutes early so you can relax, check your appearance and read any notes you may have. Check through corporate literature on display, and even chat to the receptionist - both can be vital sources of company information. Remember, nobody ever made a negative impression by arriving early – but you may ruin your chances if you are late.

Be Prepared
Bring along a folder containing extra copies of your CV, a copy of your references and paper to take notes (optional). You should also have questions prepared to ask at the end of the interview.

Show Enthusiasm and be positive
A firm handshake and plenty of eye contact demonstrates confidence. Speak distinctly in a confident voice, even though you may feel nervous. 57. Always be positive, and wherever possible, give positive responses to questions asked, beyond a simple "yes" or "no".

Listen and answer the Question Asked
One of the most neglected interviewing skills is listening. Make sure you are not only listening, but also reading between the lines and make sure you answer the right question accordingly. Remember don't be afraid if you don’t understand a question, ask the interviewer to repeat or clarify it.

Give Specific Examples
One specific example of your background is much more valuable than a number of vague stories. Prepare your responses before the interview. Give examples that highlight your successes and uniqueness. Your past behaviour can indicate your future performance.

Ask Questions
Many interviewees don't ask questions and miss the opportunity to find out valuable information. Your questions indicate your level of interest in the company or role.

Close
It is imperative that you don't leave the interview room with any nagging doubts from either side. Ask the final question "have I given you any reason today why you don't think I would be a suitable candidate for this role?" - it the interview has any doubts, by asking this final question, you can counteract and reassure him/her that you are the best candidate for the job. Finally ask the interviewer about what happens next and when a decision will be made
