It's only a discussion if the person conducting the interview has some concept of what they ask. I've been to several interviews over the years where the HR person asked questions without any understanding, questions they were obviously handed by bosses. They then hurry to write down your every word of the response, the plan being to google key terms later rather than admit ignorance now.
I had a HR interview team recently ask me about a particular rule governing the admission of evidence in administrative or arbiter proceedings. I started by asking whether they wanted me to explain admission generally or specifically how it differed between the two.... total blank faces. I asked whether I should first explain relevance ... they all nodded.
"Explain it as you would explain it to your students."
