Sample Answer
At my previous job, we decided to redesign the user interface for our company's flagship software product. The product had not been updated in several years, and there were a growing number of complaints from users about its outdated look and feel, as well as usability issues. Our goal for the redesign was not only to modernize the interface but also to address the usability concerns raised.

To determine which aspects needed improvement, I started by conducting a thorough heuristic evaluation of the existing interface to identify any usability issues. This process gave me a solid understanding of the areas where improvements would have the most impact. After that, I organized a series of usability testing sessions with existing users to gather more specific feedback on the current design. During these sessions, I took notes on what users struggled with most and asked open-ended questions to get deeper insights into their pain points.

To gather user feedback throughout the redesign process, I used a combination of methods. First, I developed a prototype of the new interface based on the findings from my heuristic evaluation and usability tests. I then conducted a new round of usability tests with the prototype, inviting both existing and potential users to participate. Their feedback helped me refine the design further.

Additionally, I set up a feedback portal where users could submit their suggestions and concerns directly, and I also reached out to our customer support team to gather any feedback they received from users. This enabled me to make data-driven decisions about which changes to implement and prioritize.

At the end of the redesign project, we had a modern, user-friendly interface that greatly improved the overall user experience. Users praised the updated design, and the number of usability-related complaints significantly decreased.

Sample Answer
At my previous job, I was tasked with redesigning the checkout process for our company's e-commerce website. The business goal was to increase conversion rates and reduce cart abandonment, while the user needs centered around a streamlined, easy-to-use checkout experience.

I began by conducting user research to understand the pain points users faced during the existing checkout process. I found that users were frustrated with having to create an account before completing their purchase. However, the business required user registration to help with customer retention and marketing efforts.

To balance both user needs and business requirements, I proposed a hybrid solution: allow users to check out as a guest, but also offer an easy opportunity to create an account at the very end of the process. This way, users would not feel forced into account creation, while the business could still capture user information for future marketing purposes.

To validate my proposed solution, I created a prototype and conducted usability testing with a group of users. The test results showed that users appreciated the option to check out as a guest, but also found the account creation process simple and non-intrusive.

The outcome of this redesign was a 17% increase in conversions and a 24% decrease in cart abandonment rates, meeting both the business goals and user needs. This project taught me the importance of empathy for users and being open to creative solutions to achieve a balance between business requirements and user expectations.
