    Application

    I applied in-person. The process took 2+ months. I interviewed at WorldQuant.

    Interview

    The whole process is really interesting and pleasant. The manager himself gave the interview and will guide you through some problem if you are stuck. They asked about some programming questions, brain teaser, and some quantitative question they meet in real life.

    Interview Questions

    • The most difficult question is a "homework" which is given before the interview. No right answer, just to see how you deal with a problem with little information.   Answer Question

    Application

    I applied through college or university. The process took 2 days. I interviewed at WorldQuant.

    Interview

    Met at a career fair at my university, had a nice chat and they scheduled me for a campus interview on the next day. Interview was a mini-quiz with multiple brain teasers. I got rejected the day after because I didnt get all of them right within the small amount of time I was given. Their engineer was friendly and interesting and I was sad I didnt go through to the next stage. I guess they want people to get all questions correct.

    Difficult Interview

    Application

    I applied through college or university. The process took 3 weeks. I interviewed at WorldQuant in October 2016.

    Interview

    Went onsite after a brief campus interview. Met with about six different people, including HR and engineers. There was a mix of algorithmic, programming language, software engineering, and behavioral questions. Each interviewer had a specific area of questioning. The whole onsite process lasted about 4 hours and all took place in the same conference room. Some interviews were in person and others were through a video call system they use internally.
