Round 2 interview questions focus on admin dashboard design and user management. You'll be asked about the roles that should exist in an admin dashboard for managing users and the UI design for the dashboard. The interviewer will ask you to describe how you would display a list of users and handle searching for users, particularly when dealing with a large number of users. You'll need to explain how you would display large sets of data, like 10,000 or 20,000 users, efficiently. When discussing adding a new user, you should outline the flow for adding a user in the system. The high-level architecture of an admin dashboard for user management should also be described, focusing on its components and structure. You'll also need to address security and scalability—how the system scales with growing data and maintains security. Role-based access and user management will come into play, where you'll discuss the roles required to manage users. The UI components for user management (like forms for adding users) should be outlined. Finally, you'll need to discuss how to implement searching and pagination for users, especially when dealing with large amounts of data.
The R1 interview questions cover a range of topics. For layout and rendering, you'll be asked how to dynamically display tasks in a board layout based on JSON data with different statuses (To-do, In Progress, Done) and how to loop through and display task cards accordingly. In dynamic interaction, you'll need to create a form for adding new tasks, ensuring the new tasks are initially placed in the 'TO_DO' column, and handle form submission to dynamically update the board. For API consumption, you'll be required to use an API to fetch tasks, display them on the board, and fetch additional user data from a separate endpoint to display in each task card. You’ll also need to manage asynchronous API calls and ensure UI updates correctly. For task management, you'll need to ensure new tasks are added to the right column, handle updates, and optimize performance when dealing with large sets of task data. In front-end security, you'll be asked why you'd use WebSockets, security best practices, and your approach to test-driven development (TDD) and maintaining code quality. The OOP task asks you to write a Circle class to calculate the area from the topmost and center points, and to write client code to use this class to calculate the radius and area.
