There is a difference between 'knowing someone' and 'knowing of someone'

There are companies who maintain an internal system where employees can create an on-line profile and be automatically notified of jobs that match their experience and interests. This system encourages not only internal promotions but lateral moves as well. Hiring from within requires a disciplined and thoughtful approach to internal interviews. Those companies encourage their managers to do substantive interviews with all internal candidates. Selecting a job candidate is often the most critical decision a manager can make. For this reason, HR team supports hiring managers to conduct rigorous interviews that include exploration of past experience, behavioral-based questions, and a discussion of the candidate's vision for the role.

There is a difference between 'knowing someone' and 'knowing of someone' and one such company who is following this principle is McGraw-Hill.
