Although I could understand that most prospective trading employees of a quantitative firm would be required to be both bright (aka Top university & math/sci Ph'D degree) and sharp (withstanding the stress), I do not know why they must also be able to code. Many posted jobs on sites such as hedgefundcenter.com for quantitative positions require that candidates be able to use programming languages such as C++. However, I would think that while it would be nice to have the two abilities (math & programming), it should not be a barrier. Why could not a firm separate the two positions? Employ one person whose skill may be developing trading ideas and the other person be able to code those ideas into a software platform. What did quant employers do to recruit candidates before much of the current technology was available to the general public (aka pre-mid 1980s)? Ciao.
