The interview loop for the UX/UI Designer role at Wise. Energy is structured to evaluate your end-to-end design capabilities, collaborative style, and alignment with our mission. The process typically ranges from three to five stages, depending on the specific team and location.

The journey begins with an initial touchpoint, which may include a structured online assessment (such as a Maki test evaluating problem-solving, attention to detail, and culture fit) or an introductory call with a recruiter. Following this, you will progress to a technical screening with a Design Lead to discuss your background. The core of the evaluation is a rigorous portfolio review panel, followed by cross-functional conversations with engineering partners and a final alignment interview with a Design Director.

This visual timeline outlines the typical progression from your initial application to the final stage. Candidates should use this roadmap to pace their preparation, ensuring they allocate ample time to refine their case studies before the intensive portfolio review. While the process is highly structured, exact timelines can vary based on scheduling and team availability.

To succeed at Wise. Energy, you must perform exceptionally well across several distinct evaluation areas. Understanding what is expected at each stage will allow you to tailor your preparation effectively.

Case Study Presentation & Visual Craft

The portfolio review is the most critical stage of the design interview process. You will be expected to present two case studies to a panel of designers, detailing your end-to-end design process and visual execution.

Be ready to go over:

• Problem Definition – How you identified the core user problem and framed the design challenge.
• Design System Utilization – Your ability to work within, contribute to, and scale established design components and UI patterns.
• Visual Execution – Your mastery of typography, color theory, spacing, and micro-interactions to create polished, modern interfaces.
• Advanced concepts (less common) – Designing for accessibility (WCAG compliance), responsive layouts across multiple device types, and complex data visualization paradigms.

Example scenarios:

• Presenting a complex dashboard design and explaining how you optimized the visual hierarchy for dense data.
• Walking through a user flow and explaining why you chose specific UI controls or navigation models over alternatives.

Cross-Functional Collaboration

Designers at Wise. Energy do not work in a vacuum. You will be closely evaluated on how you partner with engineering, product management, and data teams to bring designs to life.

Be ready to go over:

• Engineering Handoffs – How you document specs, organize Figma files, and communicate design intent to developers.
• Technical Constraint Management – How you handle situations where a proposed design is too technically complex or resource-intensive to build.
• Feedback Integration – Your process for gathering, synthesizing, and actioning feedback from non-design stakeholders.

Example scenarios:

• Discussing a past project where you had to simplify a design to meet a tight engineering release deadline without sacrificing the core user experience.
• Describing how you collaborated with an engineer to resolve a front-end rendering issue during the implementation phase.

Structured Behavioral Responses

During the behavioral portion of the panel interview, your ability to articulate your past experiences clearly and impactfully is vital. Candidates who use a structured narrative approach consistently perform better.

Be ready to go over:

• The Revised-STAR Method – Structure your behavioral answers by starting with the Result, followed by the Situation, the Task, and the Action (R → S → T → A). Leading with the outcome immediately captures the interviewers' attention and frames the rest of your story.
• Ownership and Accountability – Highlighting situations where you took the initiative to solve a problem outside your immediate scope.
• Conflict Resolution – Demonstrating empathy and constructive communication when resolving professional disagreements.

Example scenarios:

• "Tell me about a time a design project did not go as planned. What did you learn, and how did you pivot?"
• "Describe a situation where you had to lead a design initiative with very little direction."
