Parent position and position hierarchy

Summary:

Hi all, 

I would like to ask for clarification on positions in particular: 

When an employee is hired, allocated on a position that is inserted within a position hierarchy and the parent position of that position already has an incumbent. After the hiring process, I proceed with the action of assigning a manager: should I see the incumbent of the parent position?

could you please give me some suggestions?

Thanks,

Silvia
