The success of a candidate in a job interview largely depends on the interviewee s background knowledge about the activity and on the competences and skills in managing the relationship with the interviewer and his self-presentation. In this research, we seek to contribute to the description of some manifestations of this type of interactional expertise, building knowledge of practical relevance for both the interviewer and for those involved in the training of professionals. Based on studies about rhetorical discourse analysis, three interviews of candidates to a job opportunity in a transnational corporation were analyzed. The research shows that candidates differ in their level of interactional expertise, concerning the understanding of the goals of the interviewer s contributions and of the interviewee s role; the ability to make a self-presentation according to the company values and job requirements; and convincingly make claims of competences and skills tested by the interviewer.
