Preparation for London Stock Exchange Group requires a balanced approach that combines technical financial literacy with sharp analytical thinking. You are not just being assessed on what you know, but on how you structure your logic and communicate your findings under pressure.

Analytical Problem Solving – You will be evaluated on your logical approach to ambiguous problems. Use structured frameworks to break down challenges, and ensure your recommendations are supported by data or sound reasoning.

The process is designed to test both your technical capabilities and your cultural fit. It is common to encounter assignments—such as data analysis tasks or case studies—designed to simulate real-world work.

As a Business Analyst, your day-to-day will involve gathering requirements from business stakeholders—such as traders, risk managers, or compliance officers—and translating them into detailed specifications for engineering teams. You will act as a translator, ensuring that developers understand the business intent while keeping stakeholders informed of technical feasibility and progress.

You will likely spend significant time on process documentation, data validation, and post-implementation analysis.
