This question requires you to demonstrate your design thinking skills in a real-world context. The interviewer is interested in your understanding of the needs of a specific group, in this case, retirement home residents, and how you would create a store that caters to those needs and enhances their experience. Keep the following key points in mind as you formulate your response: Think about the particular needs and concerns of elderly residents. This may involve accessibility features, clear signage, intuitive layouts, product variety and types, as well as any additional services that could benefit a retirement home. Outline the design process. This should encompass understanding the users and their environment, compiling a list of needs, brainstorming potential solutions, developing a prototype, testing, gathering feedback, and making revisions. Make sure to include practical aspects such as budget, spatial requirements, and compliance with regulations.
