· During the interview show your enthusiasm and confidence. Don’t give the impression that you don’t want to be there.

·  Make sure you smile; interviewers want to know you’re happy and grateful that you got the opportunity to meet with them and that you’re actually interested in the job.

· Make sure you speak clearly so you are understood and the interviewer doesn’t have to keep asking you to repeat yourself.

· When you arrive for your interview and are introduced to the interviewers, give them a firm hand shake. Same as when you are leaving the interview give a firm hand shake and thank them. It is always a nice gesture to send a thank you note after the interview to restate your interest in the position.

When you have been approached and asked to come in for an interview, make sure you go back to the advertisement and thoroughly read it so you understand what’s required for the position. Not only should you know this information, but it gives you the opportunity to link your experience and skills with the requirements of the job.

Spend some time finding out some background information on the company you are applying for. It is always good to know about a prospective employer and what services they offer. If there is something you are unsure about and would like to know, ask the interviewer. 

Using Non Verbal Communication to Impress
What you don't say during an interview is as important as what you do say. What's important, when interviewing, is to appear professional and attentive throughout the interview process.

According to a research, 55% of another person's perception of you is based on how you look. Does it really make a difference how you dress for an interview? In many cases, it does.

The first impression you make on a potential employer can make a big difference. The first judgment an interviewer makes is going to be based on how you look and what you are wearing. That's why it's always important to dress professionally for a job interview.
