Learn MVC architecture with simple diagrams and real-world examples. Understand how the Model, View, and Controller work together to separate concerns, improve maintainability, and power scalable web and mobile applications using one of software engineering’s most fundamental architectural patterns.

A real-world async control problem inspired by Uber interviews. Given multiple promises with dependencies (e.g., A depends on B & C, B depends on D & E), design a system to execute them in the correct order. This tests your understanding of JavaScript promises, dependency graphs, concurrency control, and writing clean, scalable async orchestration logic.

Feature flags (also called feature toggles) allow developers to enable or disable features without deploying new code. Modern applications use feature flags for gradual rollouts, A/B testing, canary releases, emergency kill switches, and user segmentation. A well-designed frontend feature flag system enables rapid experimentation while keeping applications performant, scalable, and resilient.

A practical UI coding problem asked in interviews at Atlassian focuses on building a tab switcher component. Users can switch between multiple tabs, each displaying different content. As a follow-up, the selected tab should persist using query parameters so the same state is restored on refresh or when sharing the URL.

Chat systems are one of the most common real-time frontend challenges, used in messaging apps, support systems, and collaborative tools. The goal is to build a responsive UI that can send, receive, and display messages in real time while handling network delays, ordering, and state consistency. This problem tests your understanding of real-time data flow, optimistic updates, and UI synchronization.

A Kanban board is a task management system where items are organized into columns and can be moved across stages using drag and drop. Tools like Jira use this model extensively. This problem tests your ability to handle complex UI interactions, state management, and efficient updates while maintaining a smooth user experience.

A commonly asked frontend problem in interviews at Fleek, Atlassian, and Zepto focuses on building a nested folder/file structure similar to an IDE. The task involves designing a data structure to represent folders and files, and rendering it recursively in JavaScript. It tests your understanding of tree structures, recursion, and UI state handling.

A classic stack-based problem asked in interviews at Tekion. You are given an array of integers where each value represents an asteroid’s direction and weight—positive moves left to right, negative moves right to left. When two asteroids collide, the heavier one survives. The goal is to determine which asteroids remain after all collisions are resolved.
