RenTech recruited from NSA early on mostly due to Jim Simons' connections there. The recruiting they do nowadays is mostly because there are some excellent mathematicians, statisticians, information theorists, etc. there.

I have no doubt RenTech has some of the brightest out there. However, any consistently high-performing funds warrant suspicion, especially considering how many hedge funds engage in questionable activities (corporate espionage under the guise of "forensics", hacking, insider trading). Showtime's Billions isn't as far off from reality as people think.
