Why Trading and Why This Firm, With Pressure-Tested Probing of Your Experience

Two of the four rounds in this trading interview process are behavioral, each about an hour. The first opens the process; the second accompanies the final live trading game. The questions reported are: - Walk through your previous internships and most of the experiences on your resume, with persistent follow-up questions on the details of each. - Why Optiver? Why trading, and why a quantitative role? - What is the biggest challenge you have faced? - What do you think will be the biggest problem you face after joining Optiver? - In the final round: what motivates your application and what drives you, with the discussion centred on drive and collaboration. The report describes the first round as including pressure questions and says the rounds test clear logic, clear goals, honesty and the ability to adapt on the spot. ### Clarifying Questions - Should the walk-through cover every item on my resume, or should I lead with the most relevant ones and let you choose where to go deeper? - For the biggest challenge, would you prefer a professional or academic example, or is a personal one acceptable? ### Part 1 — Your experience under detailed questioning Present your internships and main resume experiences so that each one survives three or four rounds of "why" and "how exactly" follow-ups. ```hint Know what sits behind every line For each resume item, decide which decision was yours, what the result was in numbers, and what you would now do differently. ``` #### What This Part Should Cover - A concise structure for each experience: context, your part, decisions, result - A clear line between your own contribution and the team's - Honest limits ("I don't know the exact figure") and details that stay consistent under pressure ### Part 2 — Why trading, and why this firm Explain why you want to trade, why a quantitative market-making role in particular, and why this firm. ```hint Evidence over adjectives Point to things you have actually done that show the interest, rather than describing yourself as passionate. ``` #### What This Part Should Cover - Motivation for trading grounded in specific experiences - What in market making and a quantitative role fits your strengths - Firm-specific reasons drawn from what you actually learned, not prestige or pay ### Part 3 — The biggest challenge, and the biggest problem you expect Describe the biggest challenge you have faced, then the biggest problem you expect to face after joining. ```hint Pick a real difficulty Choose a challenge whose outcome was uncertain and changed because of what you did; for the second question, name a real gap and how you will close it. ``` #### What This Part Should Cover - A STAR answer with real stakes, your actions and a measurable result - A transferable lesson relevant to trading - Honest self-assessment of an expected problem, with a concrete plan ### Part 4 — Drive and collaboration In the final behavioral round, explain what drives you and show how you work with others, especially under pressure and when things go wrong. ```hint Sustained, not one-off Think of effort you kept up for months without being asked, and a moment when helping a teammate cost you something. ``` #### What This Part Should Cover - Evidence of self-directed, sustained effort and of acting on feedback - Collaboration under time pressure: communication, owning mistakes, supporting teammates - Consistency between this story and the motivation given in Part 2 ### What a Strong Answer Covers - Clear, logical, goal-directed answers that stay short enough to invite follow-ups - Honest claims whose details hold up across both behavioral rounds - Specific, evidenced motivation for trading and for this firm - Composure and adaptability when pushed back on - Drive and collaboration shown through concrete examples ### Follow-up Questions - You said you enjoy making fast decisions. Tell me about a quick decision that turned out wrong. - What would you do if the desk lost money because of a teammate's mistake? - Another candidate has faster mental arithmetic than you. Why should we hire you?
