Likely interview questions for this role
Written from this job description, not a generic list. Each one notes what the interviewer is really checking.
About your past
Walk me through your trading track record over the last two years, including your worst month.
What they are checking: Whether their profitability is real and repeatable, and whether they speak honestly about losses.
Tell me about a trade that went badly against you. When did you cut it and why then?
What they are checking: Whether they respect stops and risk limits under pressure, which protects the firm's capital.
Tell me about a time you shared an idea with another trader that helped their book.
What they are checking: Whether they will collaborate in a flat firm rather than guard every idea for themselves.
What market event in the last year changed how you trade?
What they are checking: Whether they keep learning from the market and can explain a specific adjustment they made.
What would you do
How would your strategy fit into a firm that trades a little bit of everything, and what would you need from our technology to scale it?
What they are checking: Whether they have thought concretely about moving their book here and what resources it requires.
Suppose your strategy stops working for three months straight. What do you do?
What they are checking: How they tell a temporary drawdown from a broken edge, and whether they adapt or cling.
Gelber pays on a profit split. How does that change the way you think about risk?
What they are checking: Whether they understand the incentive and still protect firm capital instead of swinging for a bigger payout.
About the work
What is your edge, and why do you believe it will last?
What they are checking: Whether they understand where their returns come from rather than crediting skill for a favorable market.
How do you size a position, and how does that change when your conviction changes?
What they are checking: Whether they have a disciplined, explainable sizing method tied to risk rather than feel alone.
How do you track your own performance beyond P&L, such as Sharpe, drawdown or hit rate?
What they are checking: Whether they measure the quality of their returns and not only the size of them.
