I recently went through the Optiver Career Kickstarter 2026 recruitment process and wanted to share some concrete, first-hand information about the Cognitive Interview stage, since there isn’t much detailed material online.
This interview happens after passing the OA and is a 1-on-1 session with an interviewer, focused almost entirely on game-based and reasoning tasks rather than traditional behavioral questions.
What the cognitive interview actually looks like:
• Fully 1-on-1, live with an interviewer
• Structured around interactive games (not LeetCode, not probability puzzles from textbooks)
• Heavy focus on decision-making under uncertainty, logic, and how you explain your thinking
• Interviewer actively reacts to your moves and reasoning, not just final answers
Candidates who perform well are invited to Amsterdam (March) for a \~1 week on-site academic/trading program, and top performers may receive a full-time offer on the spot for September 2026.
Hope this helps someone — happy to answer general questions in the comments.
