I was very transparent in my answer and made it clear this was not a question that could be answered in a job interview. To design a better site experience I would need assistance and to gather necessary information from other factors, such as user experience research and site analytics. I would need to know the platform capabilities and limitations and most importantly, more information on the ask and requirements. Without this necessary information in front of me, how can I answer such a question? You do not just design better experiences, you improve upon the experience using data; data that I obviously do not have.
