Optiver Interview 2027: Ethical Decision Question & Answer

For the Optiver ethical decision interview question, use a STAR story where doing the right thing had a real cost, and articulate the principle that guided you. In trading, integrity is infrastructure — the cost is the evidence. Commonly reported by candidates.

What This Question Assesses

This is a character test with direct job relevance. Trading firms operate on trust — with counterparties, exchanges, and regulators — and one ethical lapse can end a career and damage the firm. The interviewer wants to see that you recognise ethical dimensions proactively, that you have principles you actually apply under cost, and that you do not rationalise. A story where the "tough" decision was easy is no story at all.

Optiver Ethical Decision Interview: How to Answer

Situation: Lay out the dilemma plainly: what were the competing pressures, and what made the wrong choice tempting? A shortcut nobody would detect, pressure to hit a target, loyalty to a friend versus honesty.
Task: State the principle at stake as you saw it then — fairness, honesty, responsibility. Showing you could name the principle in the moment matters more than naming it now.
Action: Describe what you did and what it cost you: time, money, popularity, an opportunity. The cost is the evidence that the decision was genuinely tough.
Result: End with the outcome — for others and for you. If the outcome was uncomfortable, say so; comfortable outcomes make the "toughness" questionable.

An example line: "I discovered a scoring error in a competition that favoured my team — reporting it meant losing our ranking, but I flagged it to the organisers before the results were finalised. We dropped two places, and I would make the same call again, because a result built on an error I knew about is not a result."

Optiver Ethical Decision Interview: Common Mistakes

Choosing a dilemma with no real cost. If the ethical choice was also the easy choice, you have not answered the question. The interviewer is measuring what your principles cost you.
Moral grandstanding. Preaching about ethics creates distance; quiet, matter-of-fact integrity is more credible. State what you did, not how virtuous it makes you.
Over-sharing or implicating others. Keep the story focused and discreet — especially if it involves other people. Integrity includes knowing what not to broadcast.

For a market maker, this question is not philosophical — it is operational. Answer it like someone who understands that trust is the business.

FAQ

Does the example need to be finance-related? No. Academic integrity, competitions, work situations, and everyday dilemmas all work. What matters is the genuine difficulty and the principle applied.

What if I have never faced a serious ethical dilemma? Think harder — most people have: group work credit, found property, mistakes nobody noticed, pressure to cut corners. Small, real dilemmas beat invented dramatic ones.

Should I discuss the ethical framework I used? Briefly. Naming the principle (honesty, fairness) shows reflective thinking, but the story should carry the weight — not a philosophy lecture.
