- the transactional part of setting up interview loops, coordinating schedules, etc is extremely tedious for a field of 3-5 serious candidates for a given role. Internal recruiter takes all of this away from a hiring manager who has other duties.
- an internal recruiter can plow through LinkedIn to find solid candidates, identifying ones for the hiring manager to review and, if qualified, reach out to. Again, tedious work for a hiring manager with other responsibilities.
