I have used and analysed any product in jobs I was applying for in the past, and I got a good understanding of what I could bring to the table which I was very happy to spend 10-15 minutes communicating with them, being secure enough in my own abilities that they wouldn't be the type to run off and for some reason implement anything I said themselves when I know they are actively looking for resource to improve the company. We are looking for that sort of curiosity and excitement in helping build our platform out so we can reach and help even more users.

Point taken in one sense (perhaps, we'll see if we find someone great with this post), but (and I don't mean this as a slight at all) the transactional attitude you illustrate in your post is exactly what we are trying to avoid. We want creativity and curiosity!
