Interviews are like anything else in life, they take practice to perfect. The job market is highly competitive so you should always maintain a high standard of professionalism. This is guaranteed to impress your potential employer, as it will show focus and maturity.
What is Professionalism?
Professionalism is: Presentation, Punctuality and Preparation
Presentation is not just the clothes you wear, but your general presentation during
the interview. Dress for success, formal attire is the best option. Look the part
and you will be more likely to get it. Body language such as eye contact and how
you greet your interviewer are important. Shaking hands is a sign of confidence
and respect so is making regular eye contact. Always be polite not just during the
interview but to any one you may have contact with in the office or work environment.
Being on time is essential to a successful interview. Give yourself plenty of time to get to your destination, map out a route if you are unsure in any way. Being early gives you time to relax and prepare for your interview. If you are going to be late or unable to attend for any unforeseeable reason call ahead and let them know. This will show them that you are serious and that you take your commitments seriously.
Get to know the company you are hoping to work for. A little background information
can go a long way. You should research the company well before applying to it. You
must be prepared to discuss the industry, the company's relative size within that
industry and show that you know who the major players.
