You don't have the experience for the role. And that may be okay as long as you're honest and upfront about that and show a willingness to learn.

A big component of managing a dev team is performance-management- managing good and bad performers. Don't try to BS your way through that or other questions, but rather acknowledge where your gaps are and let them know that they are known unknowns rather than being oblivious to their existence.
