My son was flown around to a few top HFs during his freshman year, but after his first summer internship, he decided not to continue on that path because he thought – how should I put it – what they were doing was too “pedestrian” (he was studying CS/AI in college). I’ve also had a pretty good seat to observe what’s going on and I don’t disagree with him.
I generally don’t mind slightly off-topic discussions myself 
, but in this case, I don’t think OP has indicated that her son was interested in a job in finance. Until she does, I agree with @momofboiler1 that we shouldn’t delve too much into that familiar topic again.
