Show up in the office five minutes before your appointment time.
Do not, under any circumstances, bring a coffee beverage to the interview. Never bring one to an interview. While you may get lucky and the interviewer or receptionist may offer you a coffee or water at the office, do not bring your own beverage
Arrive prepared. Bring a pen, notebook or portfolio with paper, several résumé copies and a list of questions you would like to ask the interviewer. Many interviews start first with a request for your résumé. Removing a neat, unfolded version from your notebook is an excellent first step.
Have a conversation. The best interviews are a give and take. Come prepared to discuss the company, the role, your background, current trends in the industry, the reason for the opening and any recent business events that may impact the interviewer, role, company or industry. Companies want to hire engaged employees who have taken the time to learn about themselves and the roles for which they are applying.
Know your own resume. The hiring authority will most certaintly be picking out subjects about your professional experiences such sales performance, special skills and other topics that are on your resume. One common mistake for sales people is not being prepared to discuss their past sales performance numbers, so don’t get caught off guard by not knowing what you wrote on your resume.
