Quant;
IMHO the classification of the degree is important but what you study isn't!
Off topic i'm afraid but that is utter nonsense in my opinion, if the years I did in the city banks are anything to go by.
If anything what you studied and probably more importantly where you studied it are the crucial factors. I never saw anyone without a degree in a "proper" subject from a "proper" university even get an interview for any of the junior roles on the trading desks or equity research dept that I worked for. I'd sooner take someone with a 3rd in maths/physics/eng from a top institution over a 1st in botany/zoology/aviation related (excluding aero eng obviously).
