Product Design Lead Interview Questions
Describe a time when you had to advocate for your design decisions. How did you effectively present your rationale and convince others of the value of your design?

Sample answer to the question

In my previous role as a Junior Product Designer, I had to advocate for my design decisions when working on a mobile app project. One specific instance was when I proposed a new navigation system for the app. I effectively presented my rationale by conducting user research and usability studies to understand the pain points with the existing navigation. I created wireframes and prototypes to demonstrate how the new system would improve the user experience. To convince others of the value of my design, I prepared a comprehensive presentation highlighting the benefits, such as increased user engagement and easier navigation. I also addressed potential concerns and provided evidence from user testing. Through open and collaborative discussions, I was able to persuade the stakeholders of the value of my design decisions.

A more solid answer

In my previous role as a Junior Product Designer, I had to advocate for my design decisions while working on a mobile app project called 'TravelBuddy.' One particular instance was when I proposed a new navigation system to enhance user experience. To effectively present my rationale, I conducted in-depth user research and usability studies. I interviewed frequent travelers and observed their navigation struggles in the existing app. Based on their feedback, I created user personas and user journey maps to visualize their pain points and identify opportunities for improvement. Then, I developed wireframes and interactive prototypes using Figma to illustrate the proposed navigation system. I also prepared a persuasive presentation that showcased the benefits of the new design, such as intuitive navigation, reduced cognitive load, and faster task completion. I included real user quotes and video clips from usability testing sessions to add credibility to my argument. During stakeholder meetings, I facilitated open discussions, actively listened to feedback, and addressed concerns and questions with evidence from user testing. Through my collaborative and clear communication, I successfully convinced the team to adopt my design decisions, resulting in a more user-friendly app.

Why this is a more solid answer:

The solid answer provides specific details and examples, such as the name of the app project, 'TravelBuddy,' and the use of user personas and journey maps to visualize pain points and opportunities. It also mentions the prototyping tool used, Figma, which aligns with the required qualifications in the job description. The answer emphasizes collaboration and communication by mentioning stakeholder meetings, open discussions, and actively addressing concerns. However, it can be further improved by including information on iterative design and the impact of the design decisions on the success of the app.

An exceptional answer

In my previous role as a Junior Product Designer at XYZ Company, I had a significant opportunity to advocate for my design decisions during the development of a web-based e-commerce platform called 'ShopPro.' One particular challenge I faced was convincing the stakeholders to adopt a new checkout flow design that I believed would significantly improve the conversion rate and user satisfaction. To effectively present my rationale, I conducted extensive user research, including quantitative data analysis, user interviews, and usability testing sessions. The data revealed a high cart abandonment rate and user frustration with the existing checkout process. Armed with this research, I created detailed user journey maps, highlighting pain points and proposing solutions. I also developed interactive prototypes using Adobe XD to demonstrate the new checkout flow and its seamless integration with the existing platform. Additionally, I prepared a comprehensive business case that outlined the potential impact of the design changes on key metrics, such as conversion rate, average order value, and customer retention. During multiple stakeholder meetings, I presented my findings, confidently explaining how the new design would address user pain points, streamline the checkout process, and ultimately drive business growth. I invited stakeholders to participate in usability testing sessions, allowing them to experience the improved flow firsthand. Through continuous collaboration, transparent communication, and data-driven arguments, I successfully convinced the stakeholders of the value of my design decisions, leading to the implementation of the new checkout flow. As a result, the conversion rate increased by 15%, and customer satisfaction scores improved significantly.

Why this is an exceptional answer:

The exceptional answer goes above and beyond by providing specific details about the project, including the name of the e-commerce platform, 'ShopPro.' It highlights the candidate's ability to analyze quantitative data, conduct user interviews, and usability testing sessions. The mention of a comprehensive business case and its impact on key metrics showcases the candidate's understanding of the business aspect of design decisions. The invitation for stakeholders to participate in usability testing sessions demonstrates inclusivity and collaborative decision-making. Overall, the exceptional answer covers all evaluation areas in detail while showcasing the candidate's expertise and professional impact.
