3rd mentioned in the was a willingness to serve.

Having grown up Mormon, I'd add a 4th that wasn't mentioned in the article: deference to authority. The Mormon church is a very hierarchal organization. Orders go from the top down. People lower on the ladder should not ever contradict their leaders. When a Mormon leader asks you to do something, you expected to comply. I imagine that this mindset would make you fit in well in the FBI, at least in the lower and middle layers of the organization.
