"どのようなものですか？" means "what is it like?", which is used to ask about the detail of an object. "どのような" means "what kind of". e.g. 彼はどのような人ですか？　→ what kind of person is he? e.g. 今日はどのような天気でしたか？→ How was the weather today? もの：thing(s) です: be か： used at the end of an interrogative sentence. Hope this would help :)
