The interview is all about communication! Communication is the means by which you as an applicant will be advertising who you are, the skills and assets you offer your potential employer, reasons why you are the right candidate. Your communication allows you to make a lasting impression.

Keep in mind that employers not only value knowledge and skills in your discipline, they place importance on written and oral communication skills as well. They expect you to know about the world of work and have the ability to communicate clearly about your field as well as the unique aspects of what you have to offer their company/industry.
