The point I'm making here, is different departments/sourcing of reps can lead to different training quality.

In terms of Identifying social engineering attacks, this Is certainly the case not only with Amazon, but with almost every organization (to some degree).

Some either do not receive any training whatsoever and those who do, don't have policies In place to retrain, refresh and Improve their skill set. It's human nature to Ignore, forget or simply not absorb the training received and as such, It's Imperative to Implement It on a regular basis. As I've mentioned quite a while back on this board (In my very own words), It Is a T.A.S.K:
T= Training
A= Awareness
S= Skill set
K= Know-how
