In the conversation design portfolio, the content is more important than the medium, with a focus on showcasing case studies and demonstrating understanding of the impact on users and businesses. The best approach to presenting a CxD project involves explaining the "why" behind the design, highlighting the solutions considered, and providing a video presentation or prototype that allows for interactive exploration. Curating a portfolio requires selecting projects that demonstrate responsibilities, measuring quality, and showcasing mistakes as opportunities for growth. Conducting a portfolio review involves learning from interviews, avoiding presenting ideas versus finished products, and seeking feedback from others in the industry. Finally, success in creating a conversation design portfolio depends on focusing on the big picture of experience, self-advocating during job interviews, and highlighting strengths and dream projects.
