I once had to post a position that was specifically made for my employee, but my recruiter was awesome. I told her there was no possibility I would pick anyone else, so she suggested I make the requirements hyper specific. So, I met with my employee and we worked up a list of 10-20 things that she had done in her career and put them all in as requirements to qualify.
I received no other "qualified" applicants, so I only had to interview the one. My next meeting with her I said, "this is your official interview, do you have any questions for me?" She said "no" and I congratulated her on being selected for the role.
