My "answer" to the request for the web application was to diligently complete and submit the coding challenge, which, as requested, involved building a comprehensive, stripped-down version of PowerPoint. This took the full ten days allotted, and I included the requested "extra ideas for functionality" along with a detailed presentation outlining the architecture, design choices, and challenges faced. The expectation was that I would present and discuss this work during the final interview. However, the irony is that despite this significant effort, the application was never actually reviewed or discussed during my final interview. So, while I provided my "answer" in the form of a fully developed web app and presentation, it was ultimately not engaged with by the interviewer.
