Weeks 1-2: DSA fundamentals and practice (2-3 medium problems/day).
Weeks 1-2: Focus on Data Structures and Algorithms. Cover arrays, linked lists, stacks, queues, trees (binary, BST, AVL), heaps, hash tables, graphs. Practice algorithms like sorting (quicksort, mergesort), searching (binary search), graph traversal (BFS, DFS), dynamic programming. Aim to solve 2-3 medium problems daily.
Phase 02 of 04
Weeks 3-4: System Design principles and practice (common system design questions).
Weeks 3-4: Dive into System Design. Study concepts like load balancing, caching, database design (SQL vs. NoSQL), message queues, microservices architecture, API design, and distributed systems. Review common system design interview questions and practice designing systems like Twitter feed, URL shortener, or a chat application.
