Eclipse Trading Sales and Trading Analyst interview questions & guide 2026

The interview process at Eclipse Trading is highly standardized and rigorous. You should expect a heavy emphasis on your ability to process information quickly and accurately. The questions below reflect the patterns observed in real interview experiences.

Finance & Markets

These questions test your genuine interest in markets and your ability to keep up with current events.

• What is the current level of the HSI (Hang Seng Index) and how far is it from its annual peak?
• Who is the current Chair of the Federal Reserve?

Preparation for Eclipse Trading should be systematic and focused on speed. The firm values candidates who can prove their competence through quantitative tests before ever sitting down for a formal conversation.

Technical Proficiency – You must be fluent in options theory and market mechanics. Do not just memorize definitions; understand the "why" behind the Greeks and how they interact in complex strategies like butterflies or condors.

Mental Agility – The firm uses rapid-fire mental math and probability tests to prune the candidate pool. Practice your arithmetic until it is second nature, and ensure you are comfortable calculating expected values and betting sizes under tight time constraints.

Market Awareness – You are expected to be a student of the market. Follow central bank policy, major currency pairs, and key index levels daily. When asked for a trade idea, ensure it is grounded in current data, not just theoretical concepts.

Fit and Resilience – The culture is intense and direct. Interviewers look for candidates who are intellectually honest, quick to pivot when wrong, and capable of maintaining composure when challenged by senior traders.

The interview process is designed to be efficient and highly selective. It typically begins with a series of on-site or online written tests that serve as a hard gate; if you do not pass these, you will not proceed to the interview rounds. These tests cover mental arithmetic, probability, options theory, and general financial knowledge.

If you clear the testing phase, you will move to interviews with HR and senior traders. These are often conducted in quick succession. The atmosphere is professional but can be blunt. Be prepared for direct questioning about your thought processes and, in some cases, a practical trading simulation or "market-making game" where you must provide bid-ask spreads under time pressure.

The visual timeline above highlights the "test-first" nature of the Eclipse Trading process. You should interpret this as a requirement to be "test-ready" before you even apply. Manage your energy by preparing for the quantitative hurdles first, as these are the most common points of rejection for otherwise qualified candidates.

Mental Math & Estimation

Speed is the primary metric here. You will be evaluated on your ability to perform basic operations (addition, subtraction, multiplication, division) while under time pressure.

• Why it matters: It is a proxy for the speed at which you can calculate P&L or update a market-making position in your head.
• Preparation: Focus on drills that increase your speed. Practice estimation questions (e.g., "How many X are in Y?") to demonstrate logical decomposition of large numbers.

Options Theory

As a Sales and Trading Analyst, your primary responsibility is to support the trading desk in executing profitable strategies. You will be expected to monitor real-time market data, identify discrepancies in pricing, and assist in the management of the desk's risk.

Collaboration is key; you will interact frequently with senior traders to refine pricing models or investigate specific market movements. Your deliverables include:

• Generating and pitching actionable trade ideas based on macro-economic events or volatility analysis.
• Maintaining and updating market watchlists and internal risk reporting tools.
• Assisting in the maintenance of market-making spreads during high-volume periods.
• Participating in team-based trading simulations to refine execution speed and decision-making logic.

A strong candidate for Eclipse Trading is one who possesses both a high "raw" intellectual capability and a genuine, demonstrated passion for the markets.

• Must-have skills: Exceptional mental math speed, strong grasp of probability and statistics, foundational knowledge of options pricing, and a habit of following global markets daily.
• Nice-to-have skills: Familiarity with trading platforms, basic programming knowledge (though not strictly required for this role), and previous experience in a fast-paced trading environment or internship.
• Soft skills: High emotional intelligence, the ability to accept constructive criticism, and the confidence to express a view and defend it with data.

Q: How much time should I spend preparing for the mental math tests? A: Dedicate significant time until you are consistently hitting your targets. Many candidates fail here; it is the most common reason for rejection.

Q: Is the interview process mostly technical or behavioral? A: It is heavily technical. The initial rounds are almost entirely quantitative and market-based. Behavioral questions are used to assess your drive and "fit" for a high-intensity trading desk.

Q: What is the culture like at Eclipse Trading? A: It is a meritocracy. You will be judged on your performance, your logic, and your ability to contribute to the bottom line. It is fast-paced, direct, and can be quite demanding.

Q: How should I handle a question I don't know the answer to? A: Be intellectually honest. If it is a market fact you don't know, admit it but offer to explain how you would find the answer or what you think the drivers might be. If it is a math problem, show your working out clearly.

• Master the Basics: Do not overlook the "green book" or similar quant-prep resources; they are often sufficient for the probability and options theory components.
• Stay Updated: Follow major market news daily. If you are asked for a trade idea, have a thesis ready that includes your entry, target, and risk management plan.
• Practice Under Pressure: Use a timer for all your practice sets. The environment in the office is designed to be high-pressure; replicate that at home.
• Be Concise: When pitching a trade or answering a behavioral question, get to the point. Traders value brevity and clarity.

The Sales and Trading Analyst role at Eclipse Trading is an exceptional opportunity for those who thrive in high-stakes, quantitative environments. By mastering the core pillars of mental math, options theory, and market awareness, you position yourself as a serious candidate capable of handling the rigors of the trading floor.
