      Quantitative Analyst Interview

      Jul 9, 2025
      Anonymous Interview Candidate
      Amsterdam
      No offer
      Positive experience
      Difficult interview

      Application

      I interviewed at Optiver (Amsterdam)

      Interview

      The application process was smooth and communication from HR was timely and professional. The first round consisted of an online assessment focusing primarily on mental math and logical reasoning under strict time constraints. While the format was intense—as expected from a trading firm—the questions were fair and well-aligned with the role. Unfortunately, I did not make it past the first round, but I appreciated the clear feedback and efficient process. The whole experience reflected the company’s high standards and transparency. I'd recommend practicing with mental arithmetic tools like "Mental Math Trainer" and reviewing probability puzzles before attempting the test.

      Interview questions [1]

      Question 1

      The most important question was a mental math problem under strict time pressure, such as: “What is 73 × 87?” — without using a calculator. They really wanted to see how quickly and accurately you could think under pressure, which makes sense given the nature of the role. In addition to that, there were logic puzzles and probability questions, like: “What is the probability of drawing exactly two aces from a shuffled deck of cards?”

      Interview

      Ask questions not so hard but unprepared. The interview is not so hard but need to prepare very well for leet code data structure questions. I think the experience is below average compared to other companies.
