I think you are projecting your own biases here. OP said "DP question", there is no mention of a 'puzzle' anywhere. As I said in another comment of mine on this page, I have had to use DP in each of my last three years in real projects. If i were to hire someone for help with these, I would definitely be looking for comfort with DP styled thinking in a candidate. In order to do so I do have to simplify and abstract out the problem statement.
