Or are you referring to Disney Consumer Products internships, which might be offered in shorter 3-month summer sessions? I remember somebody from these boards that has done one, but I can't remember exactly who right now... I'll see if I can think of it.
If I were preparing for that interview, as a start I'd spend a lot of time walking the aisles of your local Wal Mart. Cosumer Products encompasses a lot of stuff and it always amazes me what's out there!
