As per default the Hiring Manager role grants a user with access to view job requisitions and job offers, when he himself is the hiring manager or when one of his subordinates in the Manager hierarchy. This access counts for the maximum number of level below the Hiring Manager.

Our HR business wants this access to be limited to only include own job requisitions and job offers and the once owned by the users having direct reporting line to him (one level down in the Manager hierarchy).
