"The most important thing we do is hire!" was a lesson from the chairman who hired me 50 years ago at Williams College. He was talking about building and maintaining an economics department, but I soon learned that it was always critical. His conviction was that if we hired well, and then mentored well, the teaching and advising and sustaining a vital department would take care of itself.
In those 50 years I've done a lot of hiring. I've been in searches as a candidate, run searches for senior administrative positions reporting to me, been part of search processes for presidents at other colleges, and have been called as a reference for countless searches where colleagues were candidates for a position.
I've responded to inquiries about my availability for positions, and watched and participated in searches that were done with, and without, search firms.
In light of the current dust-ups involving the athletic director at the University of Minnesota and the search for a superintendent for Minneapolis Public Schools, I offer the following observations.
If one uses a search firm, be sure the firm, and the individual who is leading the search from that firm, understands that this is your search, not the firm's. The firm generally likes to be in charge. It is not; the search committee, and especially its chair, is in charge. The committee should demand a change if the firm doesn't want to play by that important rule.
Search firms are businesses. They have other clients, now and in the future. They have proprietary information about candidates and institutions. They have a business to protect. Their interests and yours may not always align. That's one of the main reasons why the search committee, and especially its chair, must be in charge.
In my experience, the person you really want generally isn't looking for a job. You (and the firm) have to seek such people out. The people who apply in response to an ad often are not the ones you will want. "Search" means …. search! Building the pool of candidates is certainly the most important initial task for the committee.
Firms often like to be the ones to make calls to prospective candidates. My experience, on both sides of the hiring process, is that it makes a big difference whom I heard from. If it was from the representative of the firm, I was polite (never know when I might be in the market myself), asked questions, but generally I did not reveal much.
