The short answer: Optiver publishes its campus stages for trading: an online assessment, a behavioural interview with the recruitment team, technical interviews in its US process, and a final interview with the hiring team, which its US FAQ says is virtual. Optiver says no prior trading knowledge is needed, that mental math is necessary but not sufficient, and that quick decisions and staying cool under pressure are assessed throughout. The online assessment can be attempted only once every 8 months across all Optiver offices. Candidate reports describe probability questions, betting games with a bankroll, market-making games and a culture-fit conversation with a senior trader. Last reviewed October 2026.

A Week in the Life of a Optiver Quantitative Trader
Illustrative week · Optiver
An illustrative week for a quantitative trader, built from what Optiver says about the role in its own job postings and publications. Real weeks vary by team.
Culture notes
- Training comes first: four weeks at the Global Optiver Academy in Amsterdam, then weeks of simulated trading on live market data.
- Traders, researchers and engineers work in one loop from design to production.
- Bonuses come from a global profit pool that combines profits across desks, teams and offices.
- Optiver says quick decisions and staying cool under pressure are assessed throughout its process.
Key takeaway: Expect to train at the Academy, then price, trade and hedge a team book while building models and tools with researchers and engineers.

Optiver does not publish a level ladder. Campus hires join as graduate traders, and Optiver Europe defines experienced roles as more than 3 years of work experience. The only US trader posting with pay is an experienced systematic options role.
Pay in Optiver's US job postings
Optiver's Chicago posting states a single base salary and says the role is eligible for a discretionary bonus and a global profit-sharing pool.
| Posting | Location | US base salary range |
|---|---|---|
| Quantitative Trader/Researcher – Systematic Options Trading | Chicago, IL | $200K |
This is an experienced systematic options role that asks for 3 or more years of index options systematic trading. No US Graduate Trader or US trading internship posting was open, so there is no campus trader row. Ranges seen October 29, 2026.
Optiver quantitative trader interview process
The stages follow Optiver's US, Europe and Sydney campus FAQs and its trading postings. Assessment module names and what happens inside the interviews come mostly from candidate reports, plus two Optiver intern stories.
3 to 4 rounds
Screen
3 roundsOnline assessment
Optiver says the modules test problem solving, logic and reasoning in different formats, and that practicing mental math and strategy games may help. Its Sydney FAQ says calculators are not permitted. Candidate reports name modules such as Beat the Odds (probability), NumberLogic (sequences), Likelihood, Intervals and Orderbooks, plus short cognitive games, and say the old 80-question, 8-minute arithmetic test is absent from 2026 and 2027 invites. One candidate guide says a calculator is allowed on NumberLogic, which conflicts with the Sydney FAQ.
Tips for this round
- Practice mental math and quick strategy games, as Optiver suggests.
- Plan for no calculator; the Sydney FAQ says calculators are not permitted.
- Take it once you are ready, since you get one attempt every 8 months across all offices.
Behavioural interview
Expect motivation (why Optiver, why trading), your timelines, competing offers and start dates. Candidate reports mention light probability questions for trading candidates.
Technical interviews
The US FAQ lists technical interviews after the behavioural one, and the Career Kickstarter names a technical interview; the Sydney flow does not list a separate one. An Optiver intern story describes judging which of two traders made the better trade from data, and an open estimation question where the interviewer challenged each step. Candidate reports describe betting games with a bankroll, market-making games, probability, expected value and brainteasers.
Onsite
1 roundFinal interview day
Optiver says final interviews need no technical preparation and the dress code is casual. Candidate reports describe market-making game rounds, possibly with other candidates, and a culture-fit conversation with a senior trader or manager.
Tips for this round
- Optiver says no technical preparation is needed, so focus on composure and clear reasoning.
- Candidate reports describe a culture-fit conversation with a senior trader; prepare real examples of decisions under pressure.
Tips to Stand Out
- You do not need trading knowledge. Optiver suggests practicing quick problem solving such as mental math and strategy games before the online assessment.
- Treat the online assessment as one attempt: Optiver allows one every 8 months across all offices, so take it when you are ready and within the 7-day window.
- Mental math alone will not carry you. Optiver says quick decisions and staying cool under pressure are assessed throughout.
- Explain your thinking and stay confident. A former Optiver intern says it is fine not to know an answer, and what matters is how you react.
- Final interviews need no technical preparation, Optiver says, and the dress code is casual.
- Sydney candidates get an interview tips document with their confirmation email; read it.
Common Reasons Candidates Don't Pass
- ✗Candidate guides say some online assessment submissions are rejected automatically.
- ✗Candidate guides say trading games are scored on sizing, arbitrage and risk discipline more than on raw P&L.
- ✗A candidate guide says the final culture-fit round often rejects technically strong candidates.
- ✗A candidate guide says candidates without fast mental arithmetic rarely pass the first round.
- ✗A candidate guide says panicking after losses or turning reckless after wins is a red flag in trading games.
Based on Optiver's own pages and candidate reports.
Optiver gives no specific feedback at early stages because of volume, aims to respond within a week after each interview and can expedite for competing offer deadlines. After an unsuccessful application there is an 8-month wait for a similar role, though the US FAQ says rejected campus applicants can reapply once the next recruitment season begins. Last reviewed October 2026.
What is different at Optiver
- Campus titles differ by office: Graduate Trader in Amsterdam, Graduate Quantitative Trader in Sydney, and Quantitative Trading Internship. Experienced roles include Quantitative Trader/Researcher – Systematic Options Trading in Chicago, a hybrid of trader and researcher, and Options Trader postings in Asia. Institutional Trader, the sales-trader roles and Graduate Equity Analyst are separate tracks.
- The online assessment is a one-shot gate. Optiver allows one attempt every 8 months across all its offices, offers no retakes or resets once you start, and carries scores over to similar roles.
- New traders train before they trade. Optiver runs four weeks at the Global Optiver Academy in Amsterdam, then weeks of simulated trading on live market data before a trader joins a desk. Sydney graduates spend nine weeks in training before the floor and attend lectures through their first 12 months.
- Fit carries real weight. An Optiver intern account highlights behavioural questions and cultural fit alongside the technical part, and Optiver says final interviews need no technical preparation.
- Bonuses come from a global profit pool that combines profits across desks, teams and offices, according to the Sydney graduate posting.
- Optiver does not publish a rule on AI use in interviews; ask your recruiter. On the job, Optiver says it uses AI workflows to turn unstructured information into signals and to automate testing and monitoring, and trading interns learn to use them on trading problems.

Probability practice
Prompts we wrote for this guide around Optiver's work. They are not reported interview questions. Each answer is an outline or a worked solution.
In a betting game you start with $100 and may bet any amount, many times, on a coin that lands heads 60 percent of the time at even money. How much do you bet on the first flip?
Sample Answer
The Kelly fraction for an even-money bet is p - q = 0.6 - 0.4 = 0.2, so bet $20. Betting everything has the highest expected value per flip (+$0.20 per dollar) but almost guarantees ruin over many flips. Half Kelly, $10, gives up a little growth for much lower variance. Candidate reports say Optiver's betting games score sizing and risk discipline, so explain the trade-off out loud.
Three coins are in a bag: two are fair and one has heads on both sides. You draw one at random, flip it and see heads. What is the chance it is the two-headed coin?
Draw two cards from a standard deck without replacement. What is the chance both are aces, and the chance at least one is?
Which is more likely: at least one 6 in 4 rolls of a die, or at least one double 6 in 24 rolls of two dice?
Mental math and estimation practice
Prompts we wrote for this guide around Optiver's work. They are not reported interview questions. Each answer is an outline or a worked solution.
Quickly: 12.5 percent of 640, 7 x 0.85, and 1/16 as a decimal.
Sample Answer
12.5 percent is 1/8, and 640/8 = 80. 7 x 0.85 = 7 - 7 x 0.15 = 7 - 1.05 = 5.95. 1/16 is half of 1/8 = 0.125, so 0.0625. Knowing the eighths and sixteenths as decimals saves time on every later question.
You buy 15 call contracts at $2.40 and sell them at $2.65. Each contract covers 100 shares. What is your P&L?
Trader A bought 100 contracts at 2.00 when fair value was 2.10, and the price later fell to 1.90. Trader B bought 100 at 2.20 when fair value was 2.10, and the price later rose to 2.40. Who made the better trade?

Market making practice
Prompts we wrote for this guide around Optiver's work. They are not reported interview questions. Each answer is an outline or a worked solution.
A stock trades at 100, with zero interest rates and no dividends. The 100-strike call is 6.20 at 6.40. Where should the 100-strike put trade?
Sample Answer
Put-call parity says call minus put equals stock minus strike for European options, which is 0 here, so the put should trade around the call: about 6.20 at 6.40. If someone offered the put at 6.00, you could buy the put, buy the stock at 100 and sell the call at 6.20, paying 99.80 for a position worth exactly 100 at expiry, a locked-in 0.20.
Make a market on the number of heads in 10 fair coin flips. Then you are told the first 4 flips were all heads. What is your new market?
You buy 50 call contracts with a delta of 0.40. Each contract covers 100 shares. What is your delta, and how do you hedge it?
In a market-making game your bid is hit three times in a row and you are now long 30 lots. What do you do?
Behavioral practice
Prompts we wrote for this guide around Optiver's work. They are not reported interview questions. Each answer is an outline or a worked solution.
Why trading, and why Optiver?
Sample Answer
Optiver says no prior trading knowledge is needed, so ground the answer in how you think: fast decisions, probability and games. Connect it to what Optiver says traders do, such as setting prices, deciding how much risk to carry and building models with researchers and engineers.
Tell me about a quick decision you made under pressure with incomplete information.
What strategic game or competition do you take seriously, and what has losing taught you?
Tell me about a time you did not know the answer in front of other people.
Practice problem: find put-call parity arbitrage
pythonYou see the stock's bid and ask and, for each strike, the bid and ask of a European call and put expiring together. Assume zero interest rates, no dividends and no fees. A conversion (buy stock at its ask, buy the put at its ask, sell the call at its bid) locks in strike - stock_ask - put_ask + call_bid per share. A reversal (sell stock at its bid, sell the put at its bid, buy the call at its ask) locks in stock_bid + put_bid - call_ask - strike. Return every opportunity with a profit above zero after rounding to 2 decimals, as (strike, "conversion" or "reversal", profit), sorted by profit from highest to lowest, then by strike. Example: stock 99.95 / 100.05 and strike 100 with call 3.10 / 3.20 and put 2.80 / 2.90 gives [(100, "conversion", 0.15)].

Practice in the EngineHow to prepare
A plan for the Optiver loop, most important first:
- Prepare for the online assessment as a one-shot test: daily mental math without a calculator, sequences and quick probability, then take it within the 7-day window when you are ready.
- Practice betting games with a bankroll and size every bet; candidate reports say sizing and risk discipline are scored.
- Practice market-making games where a partner trades against you, and move your quotes as information arrives.
- Work options basics: put-call parity, delta and hedging, since Optiver trades index options and runs a systematic options team.
- Practice estimation questions where someone challenges every assumption, and questions about whether a trade was good given the data.
- Prepare behavioural answers on why Optiver, why trading and decisions under pressure; Optiver says fit carries real weight in the final.

Frequently Asked Questions
How much does an Optiver quant trader make in the US?
The only US range we found is in an experienced Chicago posting, Quantitative Trader/Researcher – Systematic Options Trading, which lists $200,000 base, asks for 3 or more years of index options systematic trading and adds a discretionary bonus and a global profit-sharing pool. No US Graduate Trader or US trading internship posting was open when we checked, so campus trader pay is not shown.
Can I use AI tools in an Optiver interview?
Optiver does not publish a rule on AI use in interviews; ask your recruiter. Its Sydney FAQ says calculators are not permitted in the online assessment.
What is on the Optiver online assessment?
Optiver says it tests problem solving, logic and reasoning in different formats and must be taken within 7 days of applying. Candidate reports name modules such as Beat the Odds, NumberLogic, Likelihood, Intervals and Orderbooks, and say the old 80-question, 8-minute arithmetic test is gone from current invites. You get one attempt every 8 months across all offices.
Do I need trading knowledge for Optiver?
No. Optiver says no prior trading knowledge is needed. It says mental math is necessary but not sufficient, and that quick decisions and staying cool under pressure are assessed throughout. Campus postings list Python as a plus, not a requirement.
Are Optiver interviews in person?
The US FAQ says all final rounds are virtual. Candidate reports describe the technical interviews as video calls with a trader. The job itself is on trading floors, postings state no remote option, and Optiver lists offices including Amsterdam, Austin, Chicago, London, New York and Sydney.
What are the entry paths into trading at Optiver?
The Quantitative Trading Internship runs 10 weeks in Amsterdam for penultimate-year students and can lead to full-time offers. Career Kickstarter - Trading 2027 is a five-day Amsterdam program in March 2027 for final-year European students, with the online assessment due 6 December 2026, and may lead to a Graduate Trader offer. Sydney runs FutureFocus, an 8-week trading internship and graduate intakes.
How is the trader role different from Institutional Trader or Graduate Equity Analyst?
Optiver traders build models and automated systems, set prices, execute trades and decide how much risk to carry and how to hedge it. Institutional Trader is a client and counterparty-facing role that asks for 2 to 5 years at a bank or prop firm. Graduate Equity Analyst sits on the Equity Options Trading desk but is a fundamental, research-driven analyst role.
