Nobody is leaving Jane Street after 18 months - straight out of college, of their own accord.
Wikipedia states: ...he returned there full-time after graduating [in 2014]. In September 2017, Bankman-Fried quit Jane Street...
Seems closer to 3 years, but it doesn't state whether he started there immediately after graduating or not.
What do you suggest are the reasons for his leaving?
> Caroline Ellison, CEO > Before joining Alameda in 2018, Caroline worked at Jane Street as a trader on the equities desk.
You seem to be talking about SBF.
Sorry if my prior message was confusing, but why would a top tier company let go one of their best performers after just a half and a year out fresh of college?
