Design Execution and Speed

These questions focus on your ability to deliver high-quality design work within constrained timeframes, a hallmark of the Marsh & Mclennan interview process.

• How do you approach a design task when you have a very limited amount of time?
• Can you walk us through your process for creating an informational mailer?

Preparation for the UX/UI Designer role at Marsh & Mclennan should focus on demonstrating both speed and precision. You should be ready to showcase a portfolio that highlights clean, professional, and client-ready work.

Technical Proficiency – You must be fluent in standard industry design software. Interviewers will look for your ability to execute tasks efficiently, so ensure you are comfortable with your tools to the point where they do not hinder your creative speed.

Time Management – Given the nature of the design challenge, you must demonstrate the ability to produce high-quality output in a short window. Practice working under self-imposed time constraints to mimic the pressure of the live design test.

Communication Skills – You will be evaluated on your ability to explain your design choices clearly. When discussing your portfolio, be prepared to articulate the "why" behind your design decisions, focusing on how they solve specific business or user problems.

The interview process at Marsh & Mclennan for the UX/UI Designer role is notably efficient and emphasizes practical application. Candidates typically undergo one-on-one interviews with team members to assess cultural fit and technical background, followed by a time-constrained design challenge. The total time commitment is generally around 2.5 hours, making it a fast-paced experience that tests your ability to perform on the spot.

This visual timeline illustrates the progression from initial behavioral and technical screens to the practical design test.

Design Methodology

This area evaluates how you translate client requirements into visual solutions. Strong performance involves demonstrating a structured approach that accounts for the target audience and the specific medium, such as print or digital.

Be ready to go over:

• Information Hierarchy – How you organize content to ensure the most critical information is prioritized for the user.
• Brand Adherence – Your ability to strictly follow corporate identity guidelines while maintaining visual interest.
• Constraint Management – How you handle limited space or time without sacrificing quality.

Example scenarios:

• "Design a mailer that explains a complex policy change to a non-technical client."
• "How would you modify a digital asset to be more effective in a print format?"

As a UX/UI Designer, your primary responsibility is to create clear, professional, and effective visual communications. You will spend a significant portion of your time producing assets that simplify complex information for clients, which requires a deep understanding of layout, typography, and color theory.

Collaboration is a core component of this role. You will interact with various departments to gather requirements and incorporate feedback. Your success depends on your ability to synthesize this input into designs that meet both aesthetic and business objectives. You are not just creating graphics; you are managing the visual narrative of the company’s services.

A strong candidate for this role possesses a blend of creative talent and operational discipline. You must be able to demonstrate that you can work effectively in a corporate environment.

• Must-have skills: Proficiency in design software (e.g., Adobe Creative Suite), strong layout skills, and the ability to work under strict deadlines.
• Nice-to-have skills: Experience with corporate branding, familiarity with UX principles in web design, and a portfolio featuring professional, client-facing work.
• Soft skills: Clear communication, the ability to take feedback gracefully, and a proactive approach to problem-solving.

Q: How difficult is the design challenge? The challenge is designed to be completed in under an hour, which makes it more about your process and speed than extreme complexity. Focus on delivering a clean, accurate, and on-brand result rather than over-complicating the design.

Q: What should I emphasize in my portfolio? Focus on work that demonstrates your ability to simplify complex information and maintain a professional, corporate aesthetic. Highlighting projects where you had to adhere to strict brand guidelines is highly recommended.

Q: Is the culture collaborative or independent? It is a mix of both. While you will have your own tasks to complete, success requires effective collaboration with team members and stakeholders to ensure your designs meet business needs.

• Review the Brand: Familiarize yourself with the visual identity of Marsh & Mclennan before your interview. Understanding their aesthetic language will give you an edge during the design test.
• Master Your Tools: Ensure your software shortcuts are second nature. Every minute counts during the timed design challenge.
• Be Concise: When answering behavioral questions, use the STAR method (Situation, Task, Action, Result) to keep your responses focused and impactful.
