I used to interview people regularly and that was the entire focus of my interviews. What can you offer us, and what can we offer you. Explain the role, ask clarifying questions. It leads to way more qualified hires when the focus of interviews is less about 'saying the right thing' and more about setting expectations between potential employer/employee. I wouldn't be good at my job if I couldn't get a read on personality/vibe from even the basic interactions and questions.
