The questions below are representative, drawn from real reported interview experiences, and may vary depending on the specific team and seniority level you target.

Product Craft and Design Execution

• Walk me through a complex design problem you solved from end to end and how you measured its success.

• Critique a common consumer application and suggest specific UX improvements.

Preparing for a UX/UI Designer loop at Grammarly requires a balanced focus on your visual craft, systemic problem-solving abilities, and collaborative mindset. Do not rely solely on your portfolio presentation; expect interviewers to dig deep into your rationale, your cross-functional partnerships, and your ability to handle ambiguous product challenges.

Role-related knowledge – This criterion evaluates your mastery of interface design, interaction patterns, and design tools. In the context of Grammarly, interviewers assess whether you can design clean, highly polished interfaces that gracefully integrate AI capabilities.

Interviewers look for structured thinking, a strong user-centric approach, and a willingness to explore multiple avenues before settling on a design direction. You can showcase this by clearly articulating the trade-offs you made during your design exercises and portfolio walkthroughs.

Leadership and collaboration – At Grammarly, design is a team sport that requires tight alignment with product managers, researchers, and engineers. Interviewers evaluate how you influence without authority, lead cross-functional initiatives, and navigate conflicting stakeholder priorities. You can stand out by sharing concrete examples of how you championed the user voice and successfully rallied a team around a shared vision.

The interview journey for a UX/UI Designer at Grammarly is comprehensive, structured, and designed to evaluate both your technical mastery and your cultural alignment. The process typically spans multiple weeks and includes an initial recruiter screen, a hiring manager conversation, a deep-dive portfolio presentation, and targeted breakout sessions or design exercises involving product management and user research. While some candidates experience a thorough and highly transparent loop where every step feels directly relevant to the role, others navigate extensive multi-round loops utilizing rigorous evaluation methods.

Portfolio and Craft Presentation

Your portfolio presentation is the anchor of the entire interview loop, serving as proof of your execution capabilities and design philosophy. Interviewers evaluate how you frame problems, how rigorously you test your ideas, and the visual quality of your shipped work. Strong performance means telling a compelling narrative that highlights your individual contributions, trade-offs, and measurable business or user impact rather than just showing pretty mockups.

Be ready to go over:

• End-to-end case studies – Deep dives into how you uncovered user pain points, mapped user journeys, and iterated on wireframes.
• Design rationale – The specific constraints, technical limitations, and business goals that shaped your final decisions.
