Quant Online Assessment Simulator
Timed, role-based OA simulations for Trading, Quant Research, and Quant Developer interviews. Modeled on candidate-reported assessment structures with section clocks, penalty scoring where the format specifies it, and no pause button. Coding attempts are timed but not scored without a judge verdict.
Trading OA Simulation
A timed two-section assessment: a mental math sprint at real screening pace, then probability and expected-value questions under the clock.

Quant Research OA Simulation
A timed two-section assessment: statistics and machine-learning questions, then probability under the clock.
Free sample at real pace · Premium unlocks the full format with saved reports
Quant Developer OA Simulation
A timed two-section assessment: C++ and systems multiple choice, then one coding problem against the clock.

How a simulation works
1.Pick your role
Trading, Quant Research, or Quant Developer. Each sim is modeled on candidate-reported structures for that role.
2.Race the section clocks
Section clocks run continuously, with a fixed 30-second break between sections. There is no pause button.
3.Manage your skips
Forward-only navigation, and some sections use penalty scoring. Knowing when to skip is part of the score.
4.Get a scored report
Scored-question accuracy, pace against the section budget, and the categories to drill. Coding attempts are not scored without a judge verdict.

Questions
What is a quant online assessment?
A timed screening test firms send before interviews: mental math or numerical reasoning for trading roles, statistics and probability for research roles, and C++/systems questions plus coding for developer roles. Candidate-reported formats run roughly 30 to 100 minutes.
Is this a real firm's assessment?
No. These are role-generic simulations modeled on candidate-reported OA structures, built and reviewed by us. We are not affiliated with or endorsed by any firm, and we never claim to reproduce any firm's actual test.
Is there a free version?
Yes. Every simulator has a free sample at the full format's pace, with no sign-up required. Premium unlocks the full-length formats with saved reports.
