Body language is important, too.
Sit up straight in your chair, lean forward slightly, and maintain eye contact. Ask meaningful questions about the position. Many employers evaluate applicants by the questions they ask. Employers like specific questions about the nature of the job, the company's plans and goals, and the abilities considered most important for the position. Answer questions by speaking in terms of the position.
