    Accepted Offer
    Positive Experience
    Difficult Interview

    Application

    I applied through college or university. I interviewed at Citadel (Chicago, IL) in August 2017.

    Interview

    Recruiter reached out to me to schedule phone screen, phone screen question difficulty was slightly above average but nothing too crazy. They really want to grill you on your data structure/algorithms knowledge in order to see if you are a good fit.

    Software Engineer Interview

    Negative Experience
    Easy Interview

    Application

    I applied through a recruiter. I interviewed at Citadel.

    Interview

    I had a phone screen interview. The interviewer called 15-20 minutes late. I must say this was a very odd interview for a Software Engineer position. For example, he questioned the value of the product I was developing at my current workplace. The interviewer seemed interested in poking holes in non-technical aspects even though it was a technical interview. My recruiter had told me that I did not need prior financial knowledge. However, the interviewer questioned my interest in the job and asked about financial terms that he knew I would not be able to answer. There was a basic C++ codility question that was asked and I had no issues with it. My feeling is that the interviewer had made up his mind even before he interviewed me but had to go through the motion because he was asked to.

    Interview Questions

    • What is a 'short'? What is a 'put'? What is a hedge fund? How much of C++11 have you used?   1 Answer

    FPGA Engineer Interview

    Negative Experience
    Easy Interview

    Application

    I applied through a recruiter. The process took a week. I interviewed at Citadel (Chicago, IL) in July 2017.

    Interview

    Contacted by head hunter, phone screen and live coderpad.

    CodePad went great, and was really expecting a third one.

    Turn out answering all questions right and having a nice conversation leads to trashing back on your abilities as a programmer on feedback!

    When the result came back, turns out im not the first one! Headhunter told me few more guys were super surprised by the feedback.

    Look to me fpga job at citadel is a fake job targeted to get many rejections to pass a GC application for one of there guys.

    Be aware not to invest too much on that one.

    Btw: I have more then 10 years experience

    I applied through a recruiter. I interviewed at Citadel (New York, NY) in June 2017.

    Interview

    -Spent an hour our on the phone with an recruiter - could not have been any nicer or more professional. Basically my background was a good fit for the role.
    -Spoke with the hiring manager about a week later. It seemed there were concerns about my being remote and not having enough experience on some products. That was pretty confusing as I thought did very well. Clearly I did not. In any case they were polite and professional throughout.
