Simplex Junior Trader interview questions

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.

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.
