Optiver Behavioral: What to Expect
- See why Optiver puts a behavioral interview right after the online assessment, and again on the final day
- Learn Optiver's five published values and use them as a lens on your stories
- Answer "Why Optiver?" without a finance background, and build stories around being wrong fast
Most engineering loops treat the behavioral interview as a formality bolted onto the end. Optiver runs it the other way. A dedicated behavioral interview sits right after the online assessment, before the deeper technical rounds. A second behavioral component returns on the final interview day. Clearing the coding assessment does not buy you a pass on it. Before Optiver commits two technical interviewers to your final day, it wants to know whether the way you think and work fits how it operates.
What it screens for reads straight off a trading floor. Optiver wants curiosity, real ownership of your decisions, and a comfort with being wrong quickly and correcting course without ego. Markets punish people who cling to a losing position. So the firm values an engineer who can say "I was wrong about that, and here is what I changed" as much as one who can defend a good call. The interview also runs both ways. Optiver frames it as your chance to decide whether the firm is right for you, so bring questions of your own.
The five values Optiver publishes
Optiver publishes five values on its own site, which most trading firms don't do. Nobody will quiz you on the list. The behavioral interview reads your stories through it. In the firm's own words:
Take ownership
Optiver frames this as owners, entrepreneurs and initiative-takers making the difference. For engineers it carries the most weight. The stories that land best show a decision you owned end to end and answered for.
Aim for excellence
A belief in continuous improvement, being your best and getting sharper each cycle. It surfaces when you talk about a system you kept refining rather than one you shipped once and walked away from.
Do our best work together
Collaboration drives the firm's success, and small teams with high autonomy only work when people raise each other's game. Stories about a disagreement you handled well, or a teammate you unblocked, speak to it.
Challenge the status quo
Optiver puts critical thought, diverse thinking, self-reflection and open feedback here. Curiosity and comfort with being wrong live here. A time you questioned an assumption, took the feedback and changed your mind maps straight onto it.
Do the right thing
Acting with integrity, exercising discipline, and making decisions that support well-functioning markets. Optiver trades its own capital in live markets. This value sits behind every question about how you behave under pressure or when nobody is checking.
Why Optiver, and no finance background needed
"Why Optiver?" and "why trading?" are the near-universal openers, and they count for more than they look. A trading firm is wary of the engineer collecting offers who would take any of them. The people who thrive here tend to go deep and stay. A generic answer about smart people and hard problems fits every other firm on your list too.
The relief is that Optiver does not expect you to arrive fluent in options or market microstructure. Its stated ideal is how you think, how quickly you learn and the kinds of problems you are drawn to. It says outright that no prior finance or trading experience is required. So the question is why this environment fits how you already work. Nobody expects you to prove market knowledge. Name something specific to Optiver. The software is the product. Latency is measured in the smallest slices of time. Feedback is tight enough to see whether a change helped, and small teams own their systems. Tie one of those to how you like to build, and no other firm's name fits your answer.
Weak: generic, could be aimed at any firm
- "Optiver is a top proprietary trading firm with a great reputation and brilliant people, and I want to work on challenging problems in a fast-paced environment."
- Nothing in it is about Optiver. Swap in any trading firm's name and the sentence still works. That tells the interviewer you would take any of those offers.
- It leans on prestige, so the motivation reads as the brand. When "why trading?" follows, this candidate has nothing specific to say.
Strong: specific to the work, honest about the pull
- "I want to build software that is the product, not a support function. At Optiver the trading system is the business. A faster or more correct path from market data to order is worth real money, and the engineering carries a weight I have not felt elsewhere."
- "I am drawn to the tight feedback. I can measure whether a change made things faster or better and iterate on numbers rather than opinions, which is already how I like to work."
- "I do not come from finance, and Optiver says that is fine, that it hires for how you think and learn. That freed me to be honest about why the environment fits me instead of performing expertise I do not have."
STAR, tuned to a trading floor
STAR gives you the cleanest structure even though Optiver does not name it. State the Situation and your Task in a sentence or two, spend most of your air on the Action you personally took, and close on a Result with something concrete. For Optiver, pick stories by the value they show. The best ones show the trading-floor instinct the firm screens for: owning a call, learning fast and correcting quickly when you are wrong.
Take a "tell me about a time you were wrong" prompt, which Optiver leans on because the answer reveals how you behave once you know. The weak version minimizes it: "I made a small call that did not pan out, but it was not a big deal." The strong version owns it. You pushed for an approach and the early numbers came in against you. You said so quickly, switched to what the data supported, and the project was better for it. Same event. One telling protects your ego. The other shows "take ownership", "challenge the status quo" and the comfort with being wrong fast that a market maker prizes.
Common questions
Does Optiver have a behavioral interview for engineers?
Yes. A dedicated behavioral interview comes right after the online assessment, before the deeper technical rounds. A second behavioral component returns on the final interview day. It is a real gate, and passing the coding assessment does not exempt you from it.
What are Optiver's values?
Five, published on the firm's own site: take ownership, aim for excellence, do our best work together, challenge the status quo, and do the right thing. There is no per-value scorecard. The round reads for them through your stories. Knowing the list helps you choose which stories to bring.
Do I need a finance background?
No. Optiver states that no prior finance or trading experience is required. It hires for how you think, how quickly you learn and the problems you are drawn to. The behavioral interview reads for learning agility and ownership. A story where you got up to speed fast on unfamiliar ground counts for more than market knowledge.
How should I answer "Why Optiver?" and "why trading?"
Name something specific to Optiver: software that is the product, latency worth real money, feedback tight enough to measure, small teams that own their systems. Tie it to how you already like to build. Be honest about why the environment fits you, and don't perform market expertise. The generic "great firm, smart people" answer fits any firm and signals you would take any offer.
