1. Rehearsing for your Interview 

• Rehearse your answers out loud before the interview to test how well prepared you are
• Identify any gaps in your delivery and answering techniques
• Rehearse with a real person. Your rehearsal partner can provide you with feedback and constructive criticism which is vital to improving your chances for success
• Rehearsing will help you build your confidence and delivery technique
• Rehearse multiple times until you feel your answers are flowing

2. Researching the Company 

• Research the company and speak about what you know about the company during interview
• Use the internet, catalogues, and other sources of information to find out as much as possible
• Speak to people that works in the company to find more about out the culture and working environment
• Research the company (using published materials and contacts) so that you are able to ask "intelligent questions".
• Reflect the image of someone working within the company 

3. Dressing for the Interview

• Whether you're going for a blue collar job or a white collar job, a creative role or a business role, there is one general rule when it comes to what to wear: dress up.
• The general consensus amongst the recruiters is that dressing to impress for that first job interview not only tells the interviewer you are serious about the job but also that you're serious about yourself.
• Even in cases where the company culture allows casual dress every day or where the role requires you to wear work denims, it's still a good idea to dress in formal office gear for the initial job interview.
• For a white collar role, a crisp business suit and tie with formal shoes for men and business suit with either skirt or pants for women is recommended. Navy blue is always a good choice as it is business like and conservative. 
• For a blue collar role in a less formal office environment, a crisp, clean shirt/top and jacket with either trousers or pants for a woman or shirt and tie and jacket for a guy with dress shoes and business socks is fine.
• As a general rule, take extra care with your appearance for a job interview. Make sure your clothes are clean and ironed.
• Wear clothes that are comfortable so you are concentrating on what is being asked of you 
• Both women and men should go light on the fragrance and aftershave.
• If in doubt, do a full dress rehearsal before the interview and get a second opinion from a friend or family member.

4. Arriving on time

• Be on time! This means not only don't be late, but don't be too early, and don't arrive with "baggage". 10 minutes early is good.
• Smile. Make eye contact and give a firm handshake

5. Check out the Competition

• Who is sitting next to you?

7. Body Language

• Body language is a form of non-verbal communication, consisting of body pose, gestures, and eye movements. Humans send and interpret such signals subconsciously.
• Some research has stated that human communication consists of 93% body language and paralinguistic cues, while only 7% of communication consists of words themselves - however, other research assert that between 60 and 70 percent of all meaning is derived from nonverbal behavior.
• Body language may provide cues as to the attitude or state of mind of a person. For example, it may indicate aggression, attentiveness, boredom, relaxed state, pleasure, amusement, besides many other cues.

10. Final tips:

• Know the company: You should be pretty well acquainted with the company and the type of work they do. You will need to do your homework and know something of their corporate culture, internal systems, business history, annual reports, mission statement etc. You can do this using several resources including company brochures, pamphlets, annual reports, newsletters and the company Web site. 
• Confirm important details: Confirm times and arrive at least fifteen minutes early to create a good first impression, travel to the interview location a day before using the same method of transport to ensure you will be on time and memorize the name of the interviewer. 
• Switch off your mobile: make sure it is switched off during the interview to avoid distractions. 
• No wet fish handshakes: Shake hands warmly with a firm grip. Handshakes have a far deeper significance than most people give credit for. 
• Ask questions: At the end of the interview, ask questions. This is your chance to really impress the interviewer with your research skills about the company and list of planned questions about the role. 
• Body language: Don’t smoke, relax, smile, look at people as you speak to them, avoid one word answers, ask questions if something seems unclear and keep your answers simple and honest. 
• Job Offer: Finally: If you accept the job, you have given your word, it is a "Verbal Contract". If you have any doubts, ask for time to think but give a time within 24 hours by which you will respond, and stick to it.
