answer:I’ve taken quite a few temporary positions in my career. Some have led to permanent positions. From my experience, there may be several options: if the agency temp job is a contract position (meaning you are an employee of the agency working on contract to the company), the company may have a policy of not directly hiring agency contract employees until the contract is finished. If this is the case, and they are still interested in having you fill the HR slot, they may put you there while you are still a contract worker, and hire you directly at the end of the 3 months. If it is a direct hire, and the HR manager knows about the situation, it would be more of an internal transfer than quitting one job for another. No one in management should see that as a bad move. Congratulations and best of luck.
