    Application

    I applied online. I interviewed at Optiver (Chicago, IL).

    Interview

    Process took a few weeks. Applied online and then interviewed at the office in Chicago in Feb 2017. Started with a mental math test online (80 questions in 8 minutes). After that there was a phone call, mostly behavioral, pretty straight forward. Third was a sequence and pattern style recognition test (30 minutes 26 questions if I recall). After those there was a technical phone interview, mostly stats/probability type questions. Final was at their office, full day of stuff, they make you re-take the online tests in person to make sure you don't cheat, and then also a couple behavioral interviews, some shadowing, one or two technical ones, and a lunch that doubles as a behavioral interview.

    Application

    I applied online. The process took 4 weeks. I interviewed at Optiver (Chicago, IL) in December 2016.

    Interview

    I had to complete a mental math test online. Follow-up was a behavioral interview - 30 minutes - quite pleasant girl on the other end. Next was a pattern matching / math test - relatively straightforward. Finally, a technical interview for 45 minutes over the phone.

    Interview Questions

    • You have 3 cards, each labeled n, n+1, n+2 and you don't know n. The rules of the game: All cards start face down. You flip one card. If you "stay", you get that card's value. If you don't "stay", then you flip another card. Again, choose to "stay" (and keep the 2nd card's value) or flip the final card and keep the final card's value. Design the optimal strategy.   2 Answers

    Difficult Interview

    Application

    I applied online. The process took 4+ weeks. I interviewed at Optiver (Chicago, IL) in September 2016.

    Interview

    I applied through their website online in late August. Received a email with the numerical test soon after. Here's the rundown of their interview process.

    1. 80 questions in 8 minutes - Very basic arithmetic. Multiple choice so you have to think and click fast. I actually had the most trouble clicking because the buttons were so small. Also, for fractions, some answer choices are not simplified.

    2. Behavioral phone interview - Went through resume and asked me basic questions like why I want to be a Trader. Also gave me the option of going with the Execution Trader or Derivatives Trader track. I chose Derivatives Trader.

    3. 26 minute quantitative skills test - A few fill in the blank math/probability questions. The rest were identify the sequence/pattern type of questions. The weirdest part for this was that there were two questions that were exactly the same. Question and answer choices were all exactly the same. Most of the questions were not hard.

    4. Technical phone interview - Went through some relevant experiences and asked why I want to be a Trader for the first 10 minutes. Basically four sections: Fermi questions, speed mental math, probability, brain teaser/math questions. The questions were pretty challenging and engaging but standard for competitive firms. Interviewer said he is looking for speed, accuracy and thought process. He also said he was most interested in the way I thought.

    --- Got cut after the tech phone interview ---

    5. Onsite - Didn't get here! Good luck to the rest of you :)

    Application

    I applied online. The process took 3 weeks. I interviewed at Optiver (Chicago, IL) in October 2016.

    Interview

    This company is terrible. They asked me to finish the mental maths part and then scheduled a phone interview with me. During the phone interview, they spent 5min to explain they don't sponsor people and hang up the phone call directly. I don't understand if you don't sponsor people, why are you wasting my time (I have specifically indicated that I'm an international student and need sponsorship in the online application). If you are also an international student, don't bother to apply for this company.

    The whole process is so unorganized and unprofessional. I don't understand who want to work for them. On the other hand, Chicago wouldn't be my first choice after all.

    Difficult Interview

    Application

    I applied online. The process took 3+ months. I interviewed at Optiver (New York, NY) in January 2016.

    Interview

    I had two interviews. The first one is about behavioral questions and willingness to relocate. The second one is purely technical.The interviewers asked me some mental math and brain teasers. It was easier than I expected. They seemed to be more interested in how you think about stuff rather than the answers you give. In the end, they gave me a question about some statistics in soccer games. I was confused by the terminology. I tried to figure out what they wanted me to solve, but the interviews got impatient. Unsurprisingly, I received a rejection next day.

    Interview Questions

    • Typical mental math and brain teasers, like 2/17 and how to transport 3000 apples.   Answer Question
