Perhaps not ignorant but maybe inexperienced for the roles and responsibilities they assumed at their new company? This is from a piece about Caroline Ellison the CEO at Alameda:

>"Before joining Alameda as a trader in March 2018, Ellison spent 19 months as a junior trader at Jane Street after graduating from Stanford University with a bachelor's degree in mathematics in 2016. In a podcast two years ago, Ellison explained that Jane Street was her first job out of college. A diehard mathematician and Harry Potter fan born of two economists, Ellison she hadn't wanted to go into trading but "just didn't really know what to do" with her life.

> "She was persuaded to join Alameda by SBF, who also previously worked for Jane Street. When she quit Jane Street, Ellison said she felt bad for staying such a short amount of time. However, this feeling quickly dissipated when she arrived at Alameda and discovered that she had "kind of more trading experience than a lot of Alameda traders," anyway."[1]
