    Application Details

    I applied online. The process took 2 daysinterviewed at Simplex Investments in February 2012.

    Interview Details

    First part of the process was to create 2-minute video answers to five questions on-line, including "What makes you the best candidate for this position?", "Estimate the number of fluorescent lightbulbs in the John Hancock Center", and "Do you think a third quantitative easing will be passed?" Two weeks later, 20 of us were brought in for testing and interviews. We were first given an easy 12-min language/math test (really easy), which was followed by a 90-min probability and reasoning test they wrote (much more difficult, tricky questions, similar to those found in "Heard on the Street"). We waited for them to grade the tests, and in 10-15 minutes they came back and read 10 names, asking the rest to leave. They then split us into two groups of 5, and observed us doing a group project where we had to decide which of three hypothetical projects (with pros and cons given) would be best for the company to undertake. Finally, they gave us individual interviews. We were each interviewed twice, both times by two people. This was more relaxed, asking questions that were more about background, or why you want to work with them and in that job. This interview process took about 4 hours, and they were very nice, pleasant, and approachable.

    Anonymous Interview Candidate in Chicago, IL
    Application Details

    I applied online. The process took 2 weeksinterviewed at Simplex Investments in February 2012.

    Interview Details

    Interview process started off with an online video test in which 5 brain teasers/personality questions were asked and you had about 2 mins to answer each. Questions were mainly open ended, others similar to those in "Heard on the Street." In order to pass to the next stage you must answer these correctly. You also need to take an 8min Wonderlic test and pass a certain amount.

    Next was a group interview at the office (nice place), which consisted of 20+ other candidates. 2 tests are given: another Wonderlic, and then their own quantitative/logic test which we were given to complete within an hour and a half. The test was very difficult, consisted of numerous problems dealing with statistics, basic option theory, and many many brain teasers. Practice up on these to stand a chance.

    Candidates were cut, and the next step was a group project. After that were personal interviews, which you were asked various personality questions and generic scenario questions. Received offer later that week. Maintained contact with HR thru email. Very courteous and willing to answer any questions.

    Overall, great experience. The process is very cutthroat, but the company/people are top notch.

    • There are 8 blue socks, 10 red socks, and 6 green socks in a drawer. If the socks are randomly distributed in the drawer (i.e. not in pairs or any other grouping), and you are blindfolded, what is the minimum number socks you must draw from the drawer in order to be certain you have at least 2 socks of the same color?   View Answer

    Application Details

    I applied online. The process took 2 weeksinterviewed at Simplex Investments in February 2012.

    Interview Details

    The first round of the process was a quick online Wunderlich test, followed by a webcam interview. A week or so after that I was called in with about 20 other candidates for the in-person interviews. There, we took a full Wunderlich test, followed by a longer, more difficult test on math, problem-solving, and basic options knowledge. After the tests, they sent half of the group home, while the rest of us stayed for a group scenario exercise, and finally 1-on-1 interviews. The whole process took about 4 hours.

    I have nothing but positive things to say about my experience, and was genuinely disappointed that I didn't receive an offer after making it so far. The office is beautiful, and the people I spoke with were bright and genuine.

    If you make it to the interviews, my only suggestion (which probably applies to all interviews) would be to always keep in mind what they would want a prospective hire to say. A couple of questions lead towards a more obvious, canned answer, but I answered honestly, and I think perhaps my candor cost me an offer.

    I applied online. The process took a dayinterviewed at Simplex Investments in January 2011.

    Interview Details

    Total interview process took about 3 days. I received a brief phone interview initially, then they sent a Wonderlic test to my email. After I submitted it, I was invited to participate in their "junior trader day" - an all day even that consisted of a longer Wonderlic, and a multiple-page math and logical reasoning test.

    The Wonderlic was fine, but the other test included the following types of questions:
    - some stat and probabilities like ones included here and from the book "Heard on the Street"
    - solving derivatives
    - basic options theory
    - word problems

    I thought I did fine, but when you're up against people pursuing phD's in math from U of Chi for a jr. trader position, your chances dwindle. There were 9 of us out of 150 applicants that made it to the final round.

    Junior Trader Interview

    Anonymous Interview Candidate
    Anonymous Interview Candidate
    Application Details

    I applied online – interviewed at Simplex Investments in October 2012.

    Interview Details

    Webcam interview consisted of general "tell us about yourself" questions, followed by brain teasers as mentioned in the previous reviews. Midway through (see unexpected question below) I wondered if I really want to work for a place that throws this kind of crazy out as a measure of a trader, instead of measuring something more relevant like -- oh, I don't know -- maybe my TRADE LOG and SUCCESS RECORD? Or whether my proprietary self-developed methodology could be turned into a profitable algorithm to contribute to the firm's profits? Maybe it was just a test of patience, and in this case I failed.

    Interview Questions
    • Most unexpected to me was they ACTUALLY asked the "how many lightbulbs in John Hancock Center" -- it's so ridiculous and unrelated to trading that I had trouble believing this was a possible question when I read reviews, and I actually managed to be unprepared. Note that the webcam interview also asks you to cut/paste URLs that you used to figure the answers out, so it's just a logic/reasoning process. I figured out lumens per square foot, how many SF in the building, how many lumens per bulb, etc. But I didn't do a thorough job of pasting the website addresses in, and the number I came up with was probably way off. They could probably sense my incredulous attitude, because midway through I wondered if I really want to work for a place that throws this kind of crazy out as a measure of a trader, instead of measuring something more relevant like -- oh, I don't know -- maybe my TRADE LOG and SUCCESS RECORD? Or whether my proprietary self-developed methodology could be turned into a profitable algorithm to contribute to the firm's profits?
