    Anonymous Interview Candidate
    Application Details

    I applied through college or university. The process took 2 weeksinterviewed at Citadel in September 2013.

    Interview Details

    First round interview on-campus: 30min behavioral, 30min technical. Nothing too difficult
    Second round on-site in Chicago: 3 hours of technical.

    They really just want someone who can code 24/7. Nothing more/less. Interviewers can be very condescending.

    Senior Accountant Interview

    Application Details

    I applied through a recruiter – interviewed at Citadel.

    Interview Details

    This process began via a recruiting Firm. Within a few days of submitting my resume, I was contacted to set up a first round interview within the same week. I was informed the first round would consist of speaking to a recruiter from HR and then the hiring Manager; however, I was told that I would only speak to the Manager if the HR discussion went well enough. I received feedback that same evening that they would like to bring me back in for a second round the following week.

    Second round involved meeting with four individuals at various levels of the team over about a two hour span. I was informed the next day that they would be extending me an offer.

    Negotiation Details
    There was no negotiation as the recruiter advised against it, but I later learned I probably could have received up to 5% more in base.

    Summer Investment Associate Interview

    Application Details

    I applied through a recruiter. The process took 5 weeksinterviewed at Citadel.

    Interview Details

    Received phone interviews with several teams, since each group does their own interviewing procedure. Then got second rounds with a few of those, and a final round with one. I was flown to Chicago for two hours of interviews with various members of the group. The questions varied significantly from group to group, ranging from quite easy to nearly impossible. The more quant-heavy groups ask more technical questions.

    Interview Questions
    • You are asked to predict movements in the S&P 500, and the correlation between your model's predictions and the actual index movement is x. What is your expected proportion of winning trades as a function of x if you invest solely on the model? Notice that if x = 1, you will always win because you can essentially predict the future.   Answer Question
    • An option is trading at an implied volatility of 30%, but its underlying asset has a volatility of 40%. What is your trading strategy? If you use the Black-Scholes formula to price this option, should you use 30% or 40% as the volatility?   View Answer

    Interview Details

    Just had one phone interview with them. The interview was quite technical in nature. Questions asked were not very tough, but covers a lot of breadth and are rather open-ended. I would be familiar with statistics and time series analysis. I felt under-prepared.
