There are 2 types of quants. 1. Quant trader: designs and implements quantitative trading strategies. Here, you'll need good econometrics / statistics skills and good understanding of financial markets. R & Python are the main 2 technologies used in that field. 2. Quant analysts: produces models to price complex financial products. Here, you'll need good stochastic calculus skills as well as solid CS knowledge (C++, F# or Python usually). In any case, you'll need some kind of university degree for anyone to trust you with either roles. With no prior financial experience, you may still find a job as a low level analyst. Interviews will have some math-based brain teasers, pure maths, and pure CS questions. It's not rare to see trained physicists and Math PHDs in these roles. Good luck
