I have a theory as to why you were brought to the interview:
When a major move is involved, the wife can be the dealkiller. Let's say they go to all the trouble to get your husband on board, then he comes home and "announces" that you're moving to Kansas. With no background, no involvement, no understanding of why this is a great opportunity, all you see is that you're going to have to move - and to Kansas of all places (speaking hypothetically off the assumption that you would not have seen Kansas and liked it at that point in the timeline). In all likelihood, you could say, "No, I'm NOT moving to Kansas." And that would be that.
Very smart of them to involve you in the process, very smart. Because if Mom doesn't wanna go to Kansas... nobody goes to Kansas
