>>940366cash equities is end of history scenario, small and normal orders are computerised, theres a cash equities desk for large/illiquid order tickets that a human trader needs to work into the market over a period of time
vanilla equity derivs (options) are also largely computerised but again there are traders in the more illiquid stuff
exotic cash equity derivatives (parisian, barrier, worst/best at delivery options, fucking mad quantum shit) are still mostly OTC, they love people with your background
and theres various equity desks with human traders in more illiquid markets (frontier EM), Delta One desks, Goldman told me they have something called an F1 Desk they just started up (???), idk various other things
FICC is just way too broad to even name, all debt is still OTC because bonds are very hard to make a centralised order book due to lack of homogeneity, so theres investment grade credit, high yield, all the structured credit trading (CLOs, CDOs, CMOs) and thats duplicated for EM and developed markets
then straight FX is like cash equities, but theres FX options, FX exotics, various shit
and ofcourse rates trading, which is all OTC and goes from vanilla to super exotic (IR swaptions etc) and thats not even debt, but its under FICC
honestly its up to you what you like, youll rotate and see, honestly people only really know about ~30% of desks in a bank, and yeah I'd take the S&T over the pure trading internship if you're not 100% sure you wanna be a trader, although im surprised the do a pure trading internship, usually its mixed, but doublecheck
