Optiver OA 求加米

Optiver runs distinct loops for its engineering and quant tracks, but both start with a fast, often-automatic online assessment (OA) sent within hours of applying.

**Software Engineer (SWE / SDE / Graduate) track**
1. **OA** — one OOP coding problem (75–90 min on HackerRank) + a 20-question CS-knowledge quiz + the Zap-N reaction games. The experienced-SWE OA instead gives two algorithm problems with a generous (up to 72-hour) window.
2. **HR / behavioral phone screen** — logistics, a project deep-dive, and motivation (~20–30 min).
3. **Virtual onsite** — typically two rounds: one coding (engineering-flavored, large skeleton code, e.g. the OptiCargo scheduler) and one system design (low-latency trading infrastructure, heavy on TCP/IP).
4. **Final behavioral** — values/fit, sometimes paired with an invitation to visit the Chicago office.

**Quant Researcher (QR) / Quant Trader (QT) track**
1. **OA** — the trading assessment: Beat the Odds probability test, Number Logic sequences, and Zap-N games. QR additionally gets three HackerRank coding problems; QT is usually games-only.
2. **Trading game interview** — a live EV/market-making betting game with a trader (often the first technical round, ~25–45 min).
3. **HR behavioral (BQ)** round.
4. **Technical round(s)** — probability/statistics brainteasers and estimation.
5. **Take-home data project** → **presentation round** (QR) drilling your methodology, pandas, and time-series work.
6. **Hiring-manager / culture call** to close.

Timelines are fast: OA invites are typically instant on application, and decisions (including rejections) often come within days of each step. Decisions on individual rounds are frequently communicated within 2–3 days.

Roles, Leveling & Sponsorship Notes

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.
