    Application Details

    I applied through college or university – interviewed at D. E. Shaw & Co. - Investment Firm.

    Interview Details

    I replied to a posting on the campus jobs board. The recruiter referred me to the Rotational Associates Position. The first round was a half-hour phone interview followed by three second-round interviews onsite. The people I spoke with were generally very smart with non-traditional backgrounds for finance. However, the process is very competitive and they seem to interview many people relative to the number of openings.

    Application Details

    I applied online. The process took 5 daysinterviewed at D. E. Shaw & Co. - Investment Firm.

    Interview Details

    First round phone Interview only. Very Prompt response on whether you advanced. The whole process took a few weeks. From the moment you submit your resume on the website, it took roughly 6-7 business days for them to contact you. Then you schedule a first round a few days out. Apparently the superday is suppose to be 4 hours and consists of many 1 on 1 interviews.

    Interview Questions

    Interview Details

    Phone interview went well, but didn't get second round. The guy was very friendly, asked me about my research project -- he had a math PhD and so we talked a lot about some of the things that I'd worked on but he didn't seem to be very impressed. We then switched to doing some basic probability that I struggled with but eventually succeeded.

    Application Details

    I applied online. The process took a weekinterviewed at D. E. Shaw & Co. - Investment Firm in November 2013.

    Interview Details

    I applied online and received an interview offer pretty early. They asked for a phone interview, and asked to have pencil and paper ready. There was no coding during the interview. First, we discussed my resume. The interviewer said he liked my resume. We then discussed one of the projects from my resume. I thought the interview was going really well. He then gave me two brain teasers to think about, and then we discussed my reasoning. The teasers are below.

    Interview Questions
    • The first question he gave me was not hard.
      1. You call to someone's house and asked if they have two children. The answer happens to be yes. Then you ask if one of their children is a boy. The answer happens to be yes again. What's the probability that the second child is a boy?

      2. (Much harder)
      You call to someone's house and asked if they have two children. The answer happens to be yes. Then you ask if one of their children's name a William. The answer happens to be yes again.(We assume William is a boy's name, and that it's possible that both children are Williams) What's the probability that the second child is a boy?

    I applied online. The process took 2+ monthsinterviewed at D. E. Shaw & Co. - Investment Firm in November 2013.

    Interview Details

    I had one phone interview, which had a few math/CS questions. I was then invited onsite, where there were 5 rounds of interviews, as well as an off-the-record lunch discussion. There were lots of probability and algorithmic questions. Knowledge of finance seemed to be a plus but not necessary. Everyone was very nice and helpful.

    Interview Details

    I had two phone interviews with DE Shaw, each lasting an hour. Neither of them was very technical at all. I expected to be asked brain teasers given that DE Shaw is known for brain teasers or at least a coding question, but instead I got a lot of behavioral questions or explaining the projects that I've done.
