And also... maybe more importantly... there's a saying (almost a joke) in the military: "You don't go to war with the forces you want, you go to war with the forces you have." (or maybe it was "people" instead of "forces" and no doubt the Air Force replaces "forces" with "very expensive weapon system manufactured by lowest-bid contractors by people who happen to live in districts represented by members of the congressional armed forces committee.") And that might be what we're getting at here.
While it would be great to get the absolute best engineer at day one, it's more likely you're going to get an engineer that requires a fair bit of training and in-the-trenches experience.
Hiring decisions tend to be a hindsight is 20/20 proposition.
