There is perhaps no better experience for a hiring manager than seeing the resume of an outstanding internal candidate land on their desk. You can fill the job immediately and, because current employees know the organization and its quirks, they require less handholding in order to get up to speed quickly. You also rarely have to pay the premium typically required to lure in external candidates. As an added bonus, hiring an internal candidate signals to other employees that they too have a future in the organization, making it more likely that they will look internally when contemplating their next career move.
