Last semester, I took a course that involved holding extensive interviews. The course was called dangerous decisions and cheerful choices, taught by Professor Barlow.
As an assignment we had to hold three interviews with a first year student, upperclassmen, and a member of the work force.
Before we could conduct the interviews we had to pass a test on ethics. The class itself focused on asking questions that pertained to the school, deciding their majors, and what their jobs might entail.
What I took away from the class was the ability to ask the right questions. What I mean by the right questions, is the wording of a question in such a manner to invoke a genuine and detailed response. The class also taught me to be comfortable meeting complete strangers and asking them potentially intrusive questions.
