Watch below to see how Zoey Zhao, Quantitative Researcher, turns her ideas into reality.


In 1986, as a Harvard freshman, Ken Griffin realized technology could be a definitive investment advantage. Convincing his dorm's janitor to let him install a satelite dish on the roof, Ken accessed live stock quotes in order to trade with real-time data. By his senior year, Ken was managing $1 million of investor money. More than 25 years later, Ken's belief in the power of technology to propel investment decisions and improve financial markets has turned into a firm that manages over $24 billion of investment capital, makes markets in 30 countries and transforms how markets work.

2014: Citadel receives "A" grade from Insitutional Investor Magazine.

    Difficult Interview


    I applied online. The process took 3 weeks. I interviewed at Citadel (Chicago, IL).


    The process was very good. Most of it was on Machine Learning. One phone interview followed by an on-site interview. On-site was 4 interviews, one algorithm, one statistics, one software and another on Machine Learning.
