We thought so too. But the (nearly) resume-blind process we settled on quickly converged on a nearly all sleeper candidate pipeline; in several years, we hired I think just 2 people that had our field on their resume. We didn't just retain all those candidates: we were knocked on our asses by how well they performed.
Recruiting is two problems: outreach and qualification. We did novel things on both fronts. For this thread, I just want to be pointing out: the changes we made to qualification were critical, instrumental, fundamental to our success. Most of our best hires could not have happened had we qualified candidates the way we did in 2009, and the way most firms do today.
