Optiver Online Assessment 2027: Full Breakdown (All Modules)
Optiver's online assessment for the 2027 intake is a 2–3 hour marathon of timed modules: 80 in 8, NumberLogic, Beat the Odds, Zap-N games, plus the newer Likelihood-List, Intervals, and Orderbook modules. It is a single sitting, one shot, no pauses between modules — and most candidates fail from poor pacing across the session, not from any one module.
The Optiver Online Assessment, Module by Module
The session opens with the mental-math gauntlet: 80 in 8 (80 arithmetic questions, 8 minutes, ~56 pass mark) and NumberLogic (26 sequences, ~25 minutes). Then come the probability and decision modules: Beat the Odds (rapid probability betting) and the Zap-N cognitive mini-games. Recent cycles added Likelihood-List (probability ranking), Intervals (range estimation), and Orderbook games (simplified bid-ask screens). The exact order and module mix vary by role — trader tracks get the heaviest quantitative load.
How to Manage 2–3 Hours Without Collapsing
Treat the Optiver online assessment as an endurance event. Take it in a quiet room with water; do the modules in the order Optiver gives them but budget mental energy deliberately — candidates consistently report the worst errors in the final 30 minutes. Do not burn your sharpest focus on 80 in 8 and coast through Beat the Odds. And know the retake rule before you start: failing means roughly 8 months before you can try again, so there is no "I'll just warm up this time."
How to Prepare for the Full Assessment
Train modules separately, then do at least two full-length dress rehearsals: all modules back-to-back under real timing, no breaks, on a laptop, with the door closed. That is where you discover that your Beat the Odds accuracy drops 20% when you are tired — something isolated practice never shows.
