Wincent Online Assessment
Wincent — a crypto algorithmic market maker — screens quant candidates with a Testlify-hosted quant test: 12 numeric-entry problems on probability and common logic, split into two sections (6 low-difficulty questions in 40 minutes, then 6 medium questions in 60 minutes). The sitting is webcam-proctored — random webcam snapshots, mandatory fullscreen, browser-extension detection — and the instructions restrict you to pen, paper, and a simple non-programmable calculator; there is nothing to code. You can skip a question but never revisit it, and the test cannot be paused. This intel is candidate-reported; the question set circulating among candidates contains no answer key, so every answer in our timed replica below was derived and independently verified by QuantVault (exact analysis cross-checked with simulation and dynamic programming).
Quant — Quant test (Testlify)
One test, two sections: questions 1-6 are the low-difficulty block (40 minutes) and questions 7-12 the medium block (60 minutes) — probability and expected value throughout, entered as plain numbers. The recurring shapes are geometric-series EV games, a Bayes witness update, Markov-chain hitting times and stationary distributions, a branching-process extinction, order-statistics tricks (darts, the classic 100-ants pass-through), linearity of expectation, and one game-theoretic hedging puzzle. Our timed replica below runs all 12 questions in the real order at the real 1h40m pace, with derived-and-verified answers and full worked solutions.

What is the format of the Wincent OA?
It runs as 1 track (Quant test (Testlify)). Quant — each timed, auto-graded where applicable.
How do I practice for the Wincent online assessment?
Work the sample questions above (each with a full worked solution), then take the interactive Wincent OA practice on QuantVault. For the full interview, see the Wincent interview-questions set.
