Android developer interview includes HR screening, technical phone round, coding challenges, system design discussion, and advanced performance questions, evaluating problem-solving, state management, architecture skills, and Flutter internals for scalable, maintainable applications.

Core Concepts: Focus on understanding and implementing key data structures like arrays, linked lists, stacks, queues, hash maps, trees, and graphs. Algorithms: Review sorting algorithms (e.g., quicksort, mergesort), searching algorithms (e.g., binary search), and understand time and space complexity (Big O notation).
