Optiver Interview Question Bank

Optiver is a market-making trading firm whose interview process is built to find fast, calibrated decision-makers under pressure. The funnel is dominated by a heavy online assessment — a probability/sequence/reaction battery for quant roles and OOP simulation coding for engineers — and the quant loop centers on a live EV betting game where speed and bet-sizing matter more than ending profit.

Beat the Odds — Probability Test

The signature Optiver quant assessment: 30 multiple-choice probability questions, ~90 seconds each, no going back. You pick the answer closest to the true value, so speed and estimation matter more than exact computation. Wrong answers are penalized.
