Yea, exactly what Bobbysamd said. Don't take the bait. I was asked a similar question at a COEX interview, except my question was, "What's going to be the worst thing about working at COEX?" I mean, what on earth kind of question is that? I know what they're getting at, if I would have said anything that sounded like a complaint, I would have been out of there! So, I tend to stick to answers that don't really have anything to do with the company. I think to that particular question I told them the worst thing would be being the new guy on the block, etc.
As far as answering what I'd change about the company, I wouldn't even go there. If I had to give an answer, I'd probably re-inerate that I would wait until I knew the people and company better, then would be more than happy to make helpful suggestions that might save the company money, or make things run smoother.
Last, you definetly want to answer these questions. If you didn't say anything, it might lead them into thinking you are afraid to speak up and give your opinion.
Just my $2 worth
