Optiver Quantitative Trader Intern interview questions

In the behavioural interview, they asked me mostly about my hobbies, how I plan to get better at them, why I like them, what my future goals for them are. In the first technical interview they presented a set of scenarios (drawing cards, rolling dice, flipping coins) and asked me to buy and sell certain outcomes based on the profit the platform was offering. Once the trades were made the scenarios would run and the profits would be calculated. They asked me to see how much profit I could make in a small window.
