Akuna Capital Online Assessment
Akuna Capital runs a different online assessment per role: Quant Researchers get a Python coding OA (HackerRank / CodeSignal) and a separate camera-proctored Math OA on EasyHire (pen and paper, verbalize your reasoning); Traders open with a 30-question HackerRank Trader Probability Test (zero-EV bet sizing, about 12 minutes), then a recorded video game round, a Trading Competition of fast market-making games and optimal-stopping coding puzzles; Software Engineers get a C++ / Python low-latency coding OA; and there is a distinct Hardware (FPGA) track. The pipeline is OA -> video interview -> phone screen -> onsite (C++, options / market-making, mental math) -> a live trading final.

Quant Researcher — Math OA (EasyHire)
The second QR screen is a camera-proctored EasyHire sitting: about five single-choice calculus and linear-algebra items where you must verbalize your reasoning before answering, then three timed probability brain-teasers (about 5 minutes each), then a short behavioral block. It leans heavily on green-book probability plus first-year calculus and linear algebra. Practice the full recoverable bank below.

Quant Researcher / Quant Trader — 2027 Coding OA (HackerRank)
The 2027-cycle coding screen ('2026 - 2027 Quant Coding Challenge (Python)'): 3 HackerRank Python questions in 120 minutes, with fullscreen forced and a multiple-monitor check. Five candidate-reported sittings (four PDF exports plus an Aug 20, 2026 photo report) reveal a shared pool - their 15 question slots contain only 8 distinct problems; closestLatencySpikes and maxPower each ran in three of the five, and getSubstring, getMaxCost and countFaults in two each. Mostly easy-to-medium strings / sorting / simulation / BFS / small DP; getMaxCost is the one genuinely tricky item, and Movie Ratings (maximizeRatings) is the DP that tripped the photographed candidate on 4 of 15 hidden tests. The timed simulation below runs one sitting exactly as it ran plus the rest of the pool.

Trader / Junior Trader — Round 3 - recorded video game round
A recorded video interview built around one fast game: a 13-row letter matrix where a random winner row sets every letter's value (its row minus the winner's). Timed best-EV wagers on standard, staggered, symbol, holed and hidden boards, plus memory callbacks on earlier boards and your own picks, and an EV-estimate finale. Our simulator replicates the full 23-question flow with fresh boards every run.
Trading Competition — Optimal-stopping / market-making games
Akuna's trading competition includes an optimal-stopping "uniform sampling" game. Implement the optimal threshold and the fair price.
