    Average Interview

    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.

    Application

    I applied through a staffing agency. The process took a week. I interviewed at WorldQuant in July 2016.

    Interview

    A staffing company introduced me to the Company and set up and phone interview. The recruiting agent said that the phone interview will be one hour and half behavioral and half technical but no coding involved. But in reality it included coding. The person who called, introduced the company and the position and described the role and asked me if I'm interested. Then asked a little bit about my resume and asked what programming languages and other technologies I am familiar with. Then shared an interactive coding document with me and asked me write a program and gave me 15 minutes. After that, asked a Linux question.

    Data Operations Interview

    Difficult Interview

    Application

    I applied through a recruiter. The process took 3 days. I interviewed at WorldQuant (Stamford, CT).

    Interview

    They asked me tons of probability questions and programming questions. This was an operations/support role and the team lead is a fresher (although, he's a PhD) with no industry experience so doesn't really know what to look out for and how to interview for a support role.

    Also, they call you in to the office, interview and drain you out for over 6 hours. So if you're going to their office, be prepared for that.
