I am currently a graduate student at a top US university (private, non-ivy). I was wondering what particular skills and classes would be looked upon as most helpful when applying to prop shops post graduation- programming? mathematics? economics? My program is in quantitative finance/risk management and I have the opportunity to take a few other graduate level courses that are quantitative based. Also, in terms of programming skills, what types of languages do most firms like to see for incoming traders/recent grads?
