The superintendent you want is not looking for a job.
He is on a project right now, doing it well, and his company is keeping him busy. He is not on the job boards. He is not updating his resume at night.
That is exactly why he is the one you want.
The people who apply to postings are not bad candidates. But if you only hire from the people who come to you, you are picking from whoever happened to be unhappy that week.
The best hires start with somebody picking up the phone and telling a busy guy about a job worth hearing about.
