something like that. obviously there are many ways to go about it. I would probably put mics in front of each person speaking. I would probably mix on a mixer right to one or two tracks. A little panning can be nice on an interview. Not hard l+r but a little seperation between voices. You could multitrack and mix/pan/etc in post but it shouldn't really be needed. Just get a decent level check or have an engineer on the mixer as it is happening to make sure nobody is to loud/quiet.
