At Citadel, your ideas and insights will put capital from the world's most sophisticated investors to work. We seek those who share our passion for problem-solving and constant reinvention.

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.

    Citadel is a place that constantly changes, as a consequence, it gives you plenty of opportunities for growth. Raise your hand, if you are ready to take charge of your career. You will be rewarded with opportunities that are pushing limits of what it means to innovate. To succeed you need to combine a deep understanding of financial markets, advance technology and focus on delivery.

    Average Interview


    I applied through college or university. The process took 1 day. I interviewed at Citadel.


    4 people half day, each interviewer asked 2-3 technical questions followed by Q&A. The interviewer is very kind and the question depends on the interview. Difficulty level is average, most questions got hints from the interviewers. Do not expect one-pass solution. Instead, try to iterate it.
