The answer you give to this question is less important than highlighting that you have a methodical, thoughtful approach to addressing business questions like these. Start out by giving a concise outline of the framework you would take in introducing a product into a foreign market. Give a thoughtful explanation of why you would take that approach, sharing your analytical thought process and using quantitative reasoning whenever possible to back up the decisions you make.

"I would need to know more details to get into the specifics of my approach to introducing a Robinhood product into a foreign market, but at a high level, I would say that the three main components of my approach would be to research, engage with local stakeholders, and evaluate. First, I would set up a team to engage in foreign market research to see how we will need to adjust our strategy to be effective in the local context. Building on this research, I would make strategic partnerships with local stakeholders to help effectively introduce the product into the new market. Finally, I would set up a comprehensive system that would allow us to both qualitatively and quantitatively evaluate the effectiveness of our product strategy. We would use those results to adjust our approach as needed."
