Considering the amount of griping about Millennials around here, I'm surprised anyone would find this question very strange.
There is a lot written about cross-generational management and the characteristics of Millennials in the work place.
If I were asked such a question, I'd say something like: I enjoy the energy that young people bring, and I appreciate their ability to adapt to challenges and new ideas. I think it is helpful to clearly explain expectations and provide detailed explanations of how various job duties and projects support the organization's strategic goals and objectives; however, those are two things that benefit employees of all ages.
