What the Final tests

Free-flowing, with curious interruptions. Fast turnaround. Optiver applies an 8-month cooling-off period after any unsuccessful application for a similar role.

Optiver calls this stage the final-day interview for campus roles.

How to prepare for the Final

Expect to be interrupted — that's good. A senior partner jumps in because he's curious or sparked a thought, not because your answer is bad. Roll with it; stay relaxed and keep it a dialogue.
Give the PERSONAL story — the specific moment that made you choose trading/industry over academia.
Frame your ambitions around ownership and an entrepreneurial drive.
Match the floor — be loud and assertive. Optiver's culture is loud, aggressive, and competitive. Speak with conviction and defend your views; timidity reads as a lack of confidence and is a real way to fail this round.

Common mistakes

It's fit, not a test you pass. This round rejects plenty of technically-strong people — it's about whether the partner thinks you belong on the floor, not right-vs-wrong. Don't let the forum horror stories psych you out; treat it as a conversation about fit.
