The Developer Week 2022 Hackathon provided an opportunity for Plushcap and Yannis Panagis to challenge themselves creatively by combining Agora's interactive experience APIs with Symbl.ai's conversation intelligence, aiming to build a smarter conversation experience. They aimed to address the challenges of tech interviews by creating InterviewToast, an internal tool offering three main features: interview preparation, feedback, and assessment, leveraging Symbl's AI for real-time insights and analysis. The solution was built using various technologies, including GatsbyJS, Agora.io, and Firebase, with WebRTC integration, which initially posed a challenge but helped Plushcap overcome his fear of the technology. Future extensions to the product include integrating Stripe for monetization and implementing interactive charts for data visualization.
