The biggest assets you can bring to any job interview when you have little or no practical experience are your communications skills, your listening skills, your flexibility and your enthusiasm. The ability to communicate effectively, maintaining good eye-contact and asking questions concisely and in a focused manner, listening actively instead of passively, thinking ahead to what you are going to say next, and the personality and attitudes that you project to the interviewer are as important—if not more so—than a good academic resume.
At the entry-level, you are hired more on your ability to communicate effectively and the willingness to learn and accept direction with enthusiasm and flexibility.
