If you have made it to the interview stage in the hiring process, the best way to prepare is by reading over the employer's job description and researching common interview questions. It’s also a great idea to think up at least two questions to ask the employer to show your interest in the role.
Be sure to dress for success as well. Business casual attire is usually recommended for interviews regardless of the position. In addition, come prepared with a printed copy of your resume and a list of references they can contact. This will help speed up the process and let them know you mean business.
