Be Prepared :  
Research the company that you will be interviewing at and learn as much as possible.  Have a few questions ready at the end of the interview to ask about the company and the position you are applying for.

Bring extra copies of your CV and references.   Bring a paper and pen to take notes.

Be on Time:

Arrive approximately 15 minutes before your scheduled interview.   Do Not be late!

Dress for Success:  

Your appearance is extremely important. Whether or not you look professional or sloppy could play a huge role on if you get hired.

Practice makes perfect:

Many career experts recommend composing written responses to frequently asked job interview questions as a way to prepare for interviews. Composing responses in writing helps you solidify effective answers in your mind so you won't be caught off guard in the interview, making you sound exceptionally prepared. Practice writing your responses to these common interview questions. 

Body Language:  

While the content of your interview responses is important, poor body language is a distraction at best and possibly a reason not to hire you at worst.

Effective forms of body language: smiling, eye contact, solid posture, active listening, nodding.

Avoid Bad Habits:

Slouching, looking off in the distance, playing with pen, fidgeting in chair, brushing back hair, touching face, chewing gum, mumbling.
