User-Centered Design

This area focuses on your ability to place the user at the center of complex financial tools. Strong performance involves demonstrating how you move from user research to functional prototypes.

Be ready to go over:

• User Research – How you validate assumptions through testing.
• Information Architecture – Organizing complex data sets for clarity.

As a UX/UI Designer, your primary objective is to turn data into clarity. You will be responsible for creating wireframes, high-fidelity mockups, and interactive prototypes that adhere to the company’s design systems. Beyond visual design, you will participate in design sprints, conduct user interviews, and contribute to the ongoing refinement of the product roadmap.

Collaboration is central to this role. You will work alongside software engineers to ensure that the interface you design is technically feasible and performs well under heavy data loads. You will also engage with product managers to define user stories, ensuring that the features being developed solve real problems for our clients in the financial sector.

A strong candidate for this role possesses a blend of high-level conceptual thinking and tactical design skills. You should be comfortable working in a fast-paced environment where precision is paramount.

• Must-have skills – Proficiency in industry-standard design tools (e.g., Figma, Sketch), a strong understanding of responsive design, and experience in building and maintaining design systems.
• Nice-to-have skills – Experience in the financial services sector, knowledge of data visualization best practices, and familiarity with front-end development frameworks (e.g., React, HTML/CSS).
• Soft skills – Exceptional communication skills, the ability to manage stakeholder expectations, and a proactive approach to problem-solving.

Q: How long does the interview process typically take? The process can span several weeks, depending on the role level and team availability. Be prepared for potential gaps between stages and follow up professionally if you have not heard back within the expected timeframe.

Q: What is the best way to prepare for the portfolio review? Focus on 2–3 projects that demonstrate your end-to-end process. Clearly state the problem, your role, the trade-offs you made, and the final impact on the user or business.

Q: Are there any specific cultural aspects to know? LSEG (London Stock Exchange Group) values professional, data-driven decision-making. Be ready to explain your design choices using metrics or user feedback rather than subjective preference.

Q: How can I differentiate myself? Show a deep interest in the financial domain. Candidates who understand the "why" behind the data they are designing for often stand out as more strategic partners to the product team.

• Prepare for non-designer questions: You may encounter interviewers from engineering or product backgrounds who ask about your resume or professional history. Stay calm and answer professionally, even if the questions feel outside the scope of design.
• Focus on the "Why": Never present a design without explaining the reasoning behind it. Your design process is just as important as the final product.
• Manage the room: If you find yourself in an interview with multiple stakeholders or representatives from partner companies, maintain a professional tone and ensure you are addressing the specific concerns of each person in the room.
