Optiver Interview Questions: What They Look For and How to Ace Them

Navigating the Optiver interview questions is the final boss for many aspiring quants. As a top-tier market maker, Optiver looks for more than just correct answers; they test for speed, composure, and sharp decision-making under pressure. This guide breaks down the real questions you'll face, from math puzzles to behavioral scenarios, and shows how Cook'd AI provides the structured, realistic practice needed to land the offer.

15+ common Optiver interview questions

Accounting & valuation questions

1. A company reports a significant non-cash impairment charge. Walk me through how this affects the three financial statements and whether it changes your fundamental valuation of the business.
2. If a company shifts from LIFO to FIFO accounting during a period of rising prices, what is the immediate impact on its reported net income and cash flow? As a trader at Optiver, does this make the company look more or less fundamentally sound?
3. What are the primary differences between Enterprise Value and Equity Value? If you had 30 seconds to decide if a stock is cheap, which would you try to calculate and why?
4. Imagine Optiver is evaluating a company that just changed its revenue recognition policy, allowing it to book revenue earlier in its sales cycle. What is the impact on its financials, and what would you look for to determine if this reflects genuine growth or just accounting manipulation?
5. How does an increase in accounts receivable, without a corresponding increase in revenue, affect a company’s cash flow? What might this signal to a firm like Optiver about the company's operational health?

Markets & macro questions

1. The VIX index suddenly spikes by 30% in pre-market trading. What are the likely root causes, and how would this event immediately change the way Optiver prices options on the S&P 500?
2. Explain the concept of 'put-call parity.' If you observe a significant deviation from this parity in the market, what arbitrage opportunity might exist and what are the risks in trying to capture it?
3. A major geopolitical event causes the price of Brent crude oil to jump by 10% overnight. Walk me through the second-order effects on equity indices, currency pairs like USD/CAD, and bond yields.
4. How does the rise of zero-day-to-expiration (0DTE) options trading impact market liquidity and volatility? From Optiver's perspective as a market maker, does this trend represent more of an opportunity or a risk?
5. If the Federal Reserve unexpectedly signals a more hawkish stance than the market anticipates, what is the immediate impact on the yield curve, and how would you expect equity sector rotations to play out in the following week?

Deal, client, & behavioral questions

1. Tell me about a time you made a significant trading error or a bad call. What was the situation, what did you do to rectify it, and what did you learn?
2. Describe a situation where you had a strong disagreement with a team member on a market view or trading strategy. How did you handle the conflict, and what was the outcome?
3. You're holding a large, profitable position that starts to turn against you. Your models say hold, but your gut says sell. Walk me through your decision-making process.
4. Beyond being a leading market maker, what specifically about Optiver's approach to technology and risk management attracts you to us over our competitors?
5. The markets are constantly evolving. Tell me about a time you had to quickly master a new financial product or trading technology. How did you get up to speed?
6. How would you describe your personal appetite for risk? Provide a concrete example where you took a calculated risk and it paid off, and one where it didn't. How does that fit with Optiver's role in the market?

Role-specific questions

1. For a Quant Trader: You are making a market on a coin flip that pays $1 on heads and $0 on tails. What is your bid-ask spread? Now, what if you know the coin is biased 60/40 towards heads? How does your market change and how do you manage your inventory risk?
2. For a Quant Researcher: How would you build a model to predict short-term volatility in a specific equity index? What data sources would you prioritize, what model families would you test, and how would you validate its predictive power to ensure it's not just overfitting?
3. For a Software Engineer: Optiver's trading systems require extremely low latency. Describe a project where you had to optimize code for performance. What was the bottleneck, what specific techniques did you use, and how did you measure the improvement?
4. For a Trader: You are the sole market maker for a newly listed, illiquid ETF. How do you determine your initial bid-ask spread? What factors would cause you to widen or tighten your spread throughout the trading day?
5. For any Quant/Trader role: Given Optiver's significant presence in options market making, what do you see as the biggest technological or market structure challenge we will face in the next two years, and how would you contribute to solving it in your role?

How to answer interview questions at Optiver

Answering questions at Optiver is a test of both intellect and composure. They value speed and precision, so your answers must be structured and direct. For behavioral questions like handling a trading error or a disagreement with a teammate, use the STAR interview method to frame your story with clarity. This keeps your answer focused and demonstrates logical thinking under pressure.

• Structure behavioral answers: Use the STAR framework (Situation, Task, Action, Result). For a question about a bad call, the 'Action' you took to rectify it and the 'Result' you learned are more important than the initial mistake.
• Think out loud on technicals: For market or quant problems, your thought process is the product. Walk the interviewer through your assumptions and logic, whether you're pricing a biased coin flip or reacting to a VIX spike.
• Quantify your impact: Vague statements fall flat. Instead of saying a decision was good, explain how it "reduced risk by X%" or "improved model accuracy by Y%." Numbers signal a quantitative mindset.
• Connect to the firm: Show you understand their business. When answering why you want this job, link your skills to Optiver's role as a market maker and their focus on technology and risk.

What Optiver looks for in candidates

Optiver is a pure meritocracy, but their definition of merit is razor-sharp. They hunt for raw quantitative horsepower, a fierce competitive drive, and unshakable composure. It’s not enough to be smart; you must be fast, accurate, and resilient when the market moves against you. They want to see concrete evidence that you live for solving hard problems, whether through math competitions, poker, or personal coding projects. Your ability to think on your feet and articulate your logic is everything.

If you're from a target university

The expectations are immense because your direct competition is just as credentialed. Your school's name is just the entry ticket.

• Differentiate with exceptional projects. A personal project that models a niche financial instrument or a high rank in a national coding competition carries more weight than another finance club membership. It signals genuine passion.
• Master your story. You need a compelling answer for why you want this job at Optiver specifically, not just any top trading firm. Research their technology stack, their role in specific markets, and connect it directly to your skills.

If you're from a non-target university

Your resume must bypass the initial screen without the benefit of prestige. It needs to scream "quant" from top to bottom.

• Create your own credentials. Pack your resume with evidence: top percentile standardized test scores (SAT/ACT Math), links to a GitHub with backtested trading strategies, or a blog where you analyze market data. This provides the signal your school doesn't.
• Get external validation. A high finish in a public Kaggle competition or a respected event like the Putnam Mathematical Competition proves you can compete at an elite level, no matter where you studied.

Optiver interview tips

Before your Optiver interview

• Drill mental math and probability puzzles until they are second nature. Speed is just as important as the correct answer at Optiver.
• Replicate the high-pressure environment. Use a timer for every practice problem and mock interview to build the muscle memory for thinking clearly under stress; it's the only way to learn how to be confident in an interview like this.
• Go beyond a generic interest in trading. Your story must connect your specific skills directly to Optiver's role as a technology-driven market maker, not just another trading firm.

During the interview with Optiver

• Maintain your composure, especially when the questions get hard. If you feel stuck, take a breath and structure your next step instead of rambling; they are testing your resilience as much as your intellect.
• If you realize you've made an error, correct it immediately and explain your new line of thinking. It signals intellectual honesty and an ability to adapt, which is more valuable than flawless but rigid thinking.
• Prepare sharp, specific questions for your interviewer about their technology or risk management to show you're already thinking on their level.

After the interview with Optiver

• Send a concise, professional follow-up email within 24 hours. Briefly thank the interviewer for their time and reiterate your interest, perhaps referencing a specific interesting problem discussed to show you were engaged.
• Immediately debrief and write down every technical question you were asked. Use this to identify weak spots in your knowledge and refine your practice for the next round or future interviews.
