Scheduling the interview took forever-- 30 days between the initial phone interview and the day at CTC. Interview process was extremely thorough-- intelligence test, case study, 4 back-to-back interviews, multiple presentations, etc. Lots of probability brainteasers. You get to see the CBOE floor. Their new offices are excellent, and it seems to be a great company to work for.

NOTE: Changed the interview process a bit, old reviews may be outdated First round - behavioral mostly (phone interview for me). I was expecting more technical questions, but the interviewer implied that they changed their interview process to make it more behavior-centric given a string of "personality mismatches" Second round - weird super day. Interviews were about 75% oddball questions, 20% behavioral, maybe 5% technical/mathy. Oddball example: what's your favorite room of your house and why? I guess these qualify as behavioral, but most were general assessment of how to think on your feet. Had 6 interviews in total. They were conversational rather than the usual interrogation type. Felt like they were trying to figure out if I was the kind of guy they would have a drink with, but also could think. I had prepped a lot of technical/quant stuff, so I was actually really thrown off and didn't perform optimally. There was also some other stuff (beside interviews) including: excel assignment, test, etc. The test was basically an SAT, so you can't really prep. It was easy though. Excel was a joke.. like all you have to do is add numbers and possibly make one chart (depends on the prompt). The HR also said nothing matters nearly as much as interviews. Also: A near direct quotation from one interview is that they didn't want someone knowledgeable about options/finance because knowledge comes with bias. They liked individuals who could think and fit in.
