The Optiver invite has a particular reputation: it arrives fast, often within days of applying, and it points at a test with a scoring rule that punishes the habits every other exam in your life rewarded. This guide covers the assessment process for the 2026-27 recruiting cycle as candidates report it: what the stages are, what each one measures, and how to train for the whole pipeline rather than just the famous first screen.
The standard caveats, stated plainly. QuantPit is independent and has no affiliation with Optiver. Everything here reflects the process as candidates have publicly and consistently described it over recent cycles, not an official specification. Formats can change between cycles, regions, and roles, so your invite email is the final authority on what you will actually face; when this guide and your invite disagree, believe the invite.
The stage most people know: 80 questions, 8 minutes
The famous first filter for trading roles is the arithmetic screen candidates call the 80 in 8: eighty mental arithmetic questions, eight minutes, with scoring commonly reported as +1 for a correct answer and -2 for a wrong one, skips free. That rule inverts school instincts. Guessing is expensive, accuracy compounds, and the winning strategy is deliberate skipping at speed, which almost nobody does naturally under a countdown.
We keep the deep treatment of this test in a dedicated guide, how to pass the Optiver 80 in 8, covering the question mix, the pacing math, and a two-week training plan. The short version of the strategy: attempt the questions you can answer with near-certain accuracy, skip fast and without regret, and train until your certain-accuracy pool covers enough questions to clear the bar.
You can also measure yourself against the field before the real thing measures you. Our free 80 in 8 benchmark reproduces the format and scoring under a real clock and shows your percentile against other candidates' anonymous attempts. Knowing whether you are at the 40th or the 85th percentile changes what your next two weeks of prep should look like.
What candidates report after the arithmetic screen
Clearing the first test does not end the automated portion. Depending on role, region, and cycle, candidates report some combination of the following stages before or alongside human interviews:
Further numerical and logic testing. A second round of timed testing appears in many reports: sometimes harder or differently structured numerical work, sometimes sequence or pattern puzzles closer in spirit to an IMC-style sequences test, sometimes probability questions with real multi-step reasoning. The common thread is time pressure plus accuracy scoring.
Game-based or behavioral components. Some candidates describe interactive exercises: simple games probing reaction, memory, risk decisions under uncertainty, or a personality and work-style questionnaire. These are hard to cram for, which is the point. The practical advice is to take them seriously, answer consistently, and not attempt to reverse-engineer an ideal persona.
A recruiter conversation. Usually short and structured: motivation, logistics, timeline, sometimes a light walk through your background. Treat "why trading" and "why this firm" as questions deserving prepared, specific answers rather than improvisation.
Trading and probability interviews. The human rounds move into expected value, market intuition, and game-style questions in the family every trading firm draws from. Our probability and expected value topic sets and the firm page cover the style; the reasoning-out-loud skills described in our Jane Street process guide transfer almost entirely.
Has the format changed for 2026-27?
The honest answer: the broad shape, a fast arithmetic screen followed by further testing and interviews, has been stable across recent cycles in candidate reports, and we have not seen credible reports of a structural overhaul for 2026-27. But firms adjust quietly, sometimes between regions in the same season: question counts, time limits, proctoring, and which stages appear at all. This is why the invite email outranks any guide, this one included. Read it twice, note the exact time limit and attempt rules, and check whether the environment requires a webcam, a quiet room, or a desktop rather than a laptop trackpad.
If your invite already arrived: the seven-day version
The full two-week plan lives in the 80 in 8 guide. Compressed to a week:
- Day 1: one full benchmark run cold, to locate your baseline score and your slowest category.
- Days 2 to 4: two 15-minute drill blocks daily on the weak categories, plus the mental math technique set: complements, left-to-right addition, fraction and percentage conversions.
- Day 5: full benchmark run two. The score matters less than the skip discipline: count how many wrong answers you logged, then halve that number as the target for the next run.
- Day 6: light drills only, plus environment setup: mouse or keyboard entry, screen size, silence, and a practice run at the same hour as your scheduled test.
- Day 7: one warm-up block, no marathon. Speed is a rested skill.
FAQ
How many questions is the Optiver math test, and how long is it?
Candidates most commonly report 80 arithmetic questions in 8 minutes for trading roles, with +1 and -2 scoring and free skips. Your invite may specify differently by role or region; the invite wins.
Is a calculator allowed?
No, by every consistent report: mental arithmetic is the entire point of the screen. Assume no calculator, no paper shortcuts beyond what the invite explicitly permits, and train accordingly.
What score do I need to pass?
Optiver does not publish cutoffs, and folklore numbers vary by year and region, so treat any specific figure with suspicion. The workable strategy is relative: our free benchmark shows your percentile against other candidates, and training until you sit comfortably in the upper portion of that field is the best available proxy.
Can I retake the assessment if I fail?
Within a single cycle, candidates generally report one shot per application. Reapplying in a future cycle is normal and common; treat a miss as scheduling information for a better-trained attempt next season, alongside the rest of the 2026-27 timeline.
How fast after applying does the test arrive?
Reports range from hours to about two weeks, with a short completion window once it lands. Apply when you are already trained, not before.
