<p>If you are in markets and you are trading options, then multivariable calculus is definitely something you will use on a daily basis.</p>
<p>As for the jobs I described I don’t have time to go into them here. I’ll just give you an anecdote from a friend I’ll call John who went to one of the aforementioned desks at a BB. So you know, he has a masters in econ from Cambridge/Oxford/LSE, won multiple international math awards, and had offers from all the top BBs as well as a couple of hedge funds:</p>
<p>John: So now that my first day on the (XYZ exotics) desk is done, it seems there’s a ton I don’t understand. Is there some book on advanced stochastic calculus or something that I could be reading in my spare time to get up to speed on the math used in this group?</p>
<p>VP: Book? (Blank stare) Book is a joke. There is no book for what we do.</p>
