In this prompt, the interviewer is asking you to create a system or service, specifically focusing on a wedding registry. A wedding registry is a curated list of items that a couple has chosen ahead of time for their guests to purchase as wedding gifts. These registries are usually handled by retail stores or online services. To tackle this question: First , you need to grasp the essential functions and users involved in a wedding registry system. Typically, there are two main users: the couple getting married, who create and manage their list, and the wedding guests, who choose and buy gifts from that list. Next , consider the features or components necessary for such a system: selecting gifts, viewing the list, making purchases, updating the list after a gift is bought, user interface design, and so on. Finally , think about how you would integrate these features or components into a unified, efficient, and user-friendly system. It is essential to clearly showcase your problem-solving abilities and your capacity to conceptualize system design in your response.
