01 / 04Phase 01 of 04
Weeks 1-2: Data Structures & Algorithms fundamentals. Practice 2-3 problems/day.
Weeks 1-2: Focus on core data structures (arrays, linked lists, stacks, queues, hash tables) and algorithms (sorting, searching, recursion, dynamic programming). Practice 2-3 problems per day. Review Big O notation for time and space complexity.
Phase 02 of 04
Weeks 3-4: Advanced DSA (Trees, Graphs). Increase problem difficulty. Intro to System Design.
Weeks 3-4: Dive into more advanced topics like trees (binary trees, BSTs, tries), graphs (traversals, shortest path), and greedy algorithms. Continue practicing coding problems, increasing difficulty. Start exploring system design concepts.
Phase 03 of 04
Weeks 5-6: System Design focus. Practice system design problems. Prepare behavioral answers (STAR).
Weeks 5-6: Concentrate on system design. Study common patterns (load balancing, caching, databases, message queues), scalability strategies, and trade-offs. Practice designing systems for common scenarios (e.g., URL shortener, Twitter feed). Begin preparing behavioral answers using the STAR method.
Phase 04 of 04
Week 7: Mock interviews. Refine answers. Research DRW.
Week 7: Mock interviews, focusing on both technical and behavioral aspects. Refine answers, practice articulating thought processes clearly, and identify any remaining weak areas. Research DRW thoroughly.
