How would you implement a stack using another data structure?

Let's say you have a complex e-commerce system composed of several subsystems: a user authentication service, a product catalog, a shopping cart, an order processing module, and a payment gateway. Each of these subsystems interacts with others to provide the complete shopping experience. How would you approach testing this entire system to ensure it functions correctly, is reliable, and meets performance expectations? Please describe the types of tests you would perform, the tools you might use, and how you would handle potential challenges like coordinating testing across multiple teams or simulating real-world user traffic.

Let's discuss your previous projects in detail. I'd like to understand your role, the challenges you faced, and the solutions you implemented. To help me understand the scope of your work, please walk me through a project where you significantly contributed to the success of the team or the company. Elaborate on the technologies you used, the architecture you designed (if applicable), and the methodologies you followed (e.g., Agile, Waterfall). Be prepared to discuss specific technical decisions you made and the trade-offs you considered. For instance, can you describe a situation where you had to choose between performance and scalability, and how you arrived at your decision? Or, tell me about a time when you had to debug a particularly complex issue in a project? What steps did you take to identify the root cause, and how did you go about fixing it? I am also interested in hearing about any failures or setbacks you experienced during a project. What did you learn from those experiences, and how did you apply those lessons in subsequent projects? Finally, can you quantify the impact of your contributions to the project in terms of metrics such as improved performance, reduced costs, or increased user engagement?
