Interesting. How far removed were you from regulated activities ? Did your firm and/or role have a retail facing element or only institutional ?

Most places I know of would not only have the sort of induction training you imply, but regular refreshers for anyone involved in regulated or at-risk activities.

We had the refreshers as well. We theoretically had access to fairly extensive private data. Not without leaving a pretty extensive paper trail, but the access was there.

Mandatory insider trading training is required at my FAANG employer. I think it's 1-2 hours rather than 4 hours, but still substantial.
