When I get my first job interview, I’ll have to do everything possible to get the impression that I’m a fantastic worker and real professional. So you have to look confident by looking into the interviewer’s eyes and speak with a strong tone of voice. You have to give him the idea of being someone trustable, sociable by sitting right and straight in the chair. You have to show that you know what you are talking about and that you’re the right person for the job! All these factors are crucial to get the attention of the interviewer.
