It’s easy to tell which managers were promoted from within and which were external hires with no hands on experience.
I don’t think hands on experience is necessary, but you need to have a comprehensive understanding of the work being done by people you oversee. That becomes increasingly difficult as your position moves you from the front line, which I think is one reason upper management and executives often seem like aliens compared to the rank and file and lower management.
