First interview was face-to-face with the hiring manager and the current rep in the territory. Interview was formal and consisted of STAR questions. Make sure you relate your current and past experience with what the potential job duties are. Second interview was a phone interview with a specialty rep that I would be working with. That interview was casual and basically just went over my resume. Third interview was face-to-face with the area director. This was a difficult interview. He asked me "How do you manage your funnel?" and "How do you integrate strategic and conceptual selling into your sales presentation?" Final interview was phone conversation with the hiring manager and was casual.
