Quant interview simulation
Practise the way the screen actually works.
A ruthlessly audited simulation engine: over 4,100 mathematically verified procedural scenarios and a 3D open-outcry pit, with 60 timed games and 34 full mock screens.
The Pit™ · live now
The market used to be a room full of people shouting.
The Pit is a 3D open-outcry floor: quote a two-sided market out loud, get hit, and carry the position. Click into it to play right here, or open it full screen.
What’s inside
Three things, and they work together.
Probability, market making, mental math, statistics, algorithms, risk, econ and actuarial. Three to eight minutes a run, scored every time.
34full mock screensModelled on publicly reported formats from Optiver, SIG, Jane Street, Citadel, DRW and twenty more. Clock, answer sheet, flag for review.

Know where you stand
One sitting tells you what to practise next.
Six sections: patterns, logic, estimation, probability, reaction and task switching, and working memory. You get 13 subskill scores with percentiles, your fit for trader, researcher, developer and risk roles, and a growth plan for every weak spot.
Take the diagnostic →Your plan, drawn as a road
The sitting becomes a route you can follow.
Each weak spot becomes a stop on the road: a specific game, in order, with a retake date at the end. This is the plan built from the example result above, two stops in.

Market making - Clear the campaign to level 10 - multi-leg hedging on a clock
Market making cost you 29 of the 72 points you left behind - the biggest single gap.
Test yourself
Sit the real thing before the real thing.
34 full-length sittings, each modelled on one firm’s reported format, with negative marking where the real one has it. Fresh questions every attempt; three questions of any sitting are free.
Mock interviewSay the answer out loud, like you will on the day.Talk through the problem - your assumptions, your estimate, what you would do if the number moved - and get graded on the reasoning. The round most candidates never practise.

Does the duck match the arrows?
Crossroad Multitasker is thirty-five trials of four sums and a moving road, and the rule flips without warning. The score is how much slower you are right after it does, which is exactly what an eight-minute screen punishes.
Play the duck →Does the duck match the road arrows?
Thirty-five trials. The rule flips without warning - the score is how much slower you are right after it does.
Market making
Find the combination that nets to zero.
Basket Arbitrage hands you a few tradeable cards, each with a bid and an ask, and the job a desk actually does: buy the components, sell the bundle, pocket the gap. Levels are generated fresh, and the game notices when you leave money on the table.
Play Basket Arbitrage →Arithmetic under a rule change
Fly through the right answer.
Flappy Math is a ninety-second run with two rules: in the air, fly through the gap with the right answer; on the floor, hop the obstacles that do not match your colour. The rule switches every eight to fifteen seconds, and the score weighs the three seconds after each switch most.
Play Flappy Math →Two rules, one bird, and the rule flips.
Coding challenges
Correct but slow still fails.
Algorithm Arena is eleven desk problems across four tiers: you write the function in the browser, a harness runs it against hidden cases, and a correct answer that is too slow does not pass. Four quick questions afterwards check that you understand why it did.
Enter Algorithm Arena →Maximum Drawdown
Given an array of historical prices, write maxDrawdown(prices) returning the largest loss from a peak to a later trough. If the price never drops, return 0.
peak to prices[0], not 0?What it is worth
The job on the other side pays more than almost any first job there is.
A graduate trading screen is a few hours of your life and a pass's worth of prep, standing between you and one of the best-paid first jobs anywhere. That trade is the whole reason to take the practice seriously.
Thirty minutes a day for eight weeks - the usual run-up to a screen.
The Recruiting Season pass: three months of everything, one charge.
Reported first-year pay at the top trading firms. Jane Street’s own posting lists a $300,000 base, before bonus.
Outcry does not get you the job - the screen still has to be passed, and no practice platform can promise an offer. It gets you ready for the screen. Pay figures: Jane Street, Quantitative Trader (NYC) and reported first-year totals at top firms, e.g. Young and Calculated, 2026.

Why we made it
We prepared off a PDF. The screen had a clock.
The real thing was eighty arithmetic questions in eight minutes and a market-making round where the person opposite knew whether the coin was fair. Every question and every scoring anchor here is checked by a mathematics PhD.
- 01Nothing to memorise - problems are generated, not stored.
- 02Every run has a clock, because every screen does.
- 03Tickets, not stars - one per correct answer, spent at a prize counter, never bought.
- 04Free warm-up drills with no account; Outcry Pro opens everything.

Questions
Before you insert a coin
Is Outcry free?
The warm-up drills are free with no account and no card: mental math, sequences, classic Fermi and Duck Duck Dash. Every other game, the mock screens and the full diagnostic come with a pass.
Who is checking the math?
A mathematics PhD checks every question and every scoring anchor before it ships. The team behind Outcry includes an Erdős Institute Award Winner, a Math Olympiad Competitor and industry-credentialed quant talent, and every answer key is recomputed independently rather than trusted.
Which firms does this prepare you for?
The mock sittings are modelled on publicly reported formats from Optiver, SIG, Citadel, DRW, Hudson River Trading and Two Sigma, plus actuarial, risk and economic consulting screens. The skills underneath - mental math, probability, market making, statistics and coding - come up in every trading and quant research screen.
Where should I start with quant prep?
Arithmetic first. It's the one part that improves with repetition alone, and most trading screens open with it. After that, probability, then market making, and full sittings once you have a few weeks of runs to compare against. The quant prep plan lays this out over eight weeks.
How is this different from a question bank?
The questions are generated fresh each run, so there is no set to memorise, and you answer them under a clock instead of reading them off a page. At the end of each run you get accuracy by skill.
Do I need an account?
Not to play. Guest tickets are stored in the browser you earned them in. An account keeps them and carries your progress between devices.
What are tickets for?
One ticket for each question you get right. You can't buy them. They spend at the prize counter on name colours, titles and a full day of access to every game, and the rest of the time they work as your running score.
How much is a pass?
Interview Crunch is $69.99 for a month, Recruiting Season is $149.99 for three months, and the Quant Offer Pass is $249 for a year. Every pass opens everything: every game, all the mock screens, the mock interview, and your full diagnostic breakdown and plan. Each is a single charge that does not renew. The warm-up drills stay free either way.

Every run timed, scored and audited.
