01 / 06Phase 01 of 06
Weeks 1-2: Data Structures (Arrays, Lists, Maps) & Basic Algorithms (Sorting, Searching). Complexity Analysis.
Weeks 1-2: Focus on core data structures like arrays, linked lists, stacks, queues, and hash maps. Practice basic algorithms such as sorting (quicksort, mergesort) and searching (binary search). Cover time and space complexity analysis.
Phase 02 of 06
Weeks 3-4: Trees & Graphs (BFS, DFS, Dijkstra's). Dynamic Programming.
Weeks 3-4: Dive deeper into trees (binary trees, BSTs, AVL trees) and graphs (traversals like BFS, DFS, shortest path algorithms like Dijkstra's). Introduce dynamic programming concepts with examples.
Phase 03 of 06
Weeks 5-6: System Design Fundamentals (Scalability, Caching, Databases, APIs).
Weeks 5-6: Begin system design preparation. Study concepts like scalability, availability, load balancing, caching strategies, database design (SQL vs. NoSQL), and API design. Work through common system design problems.
Phase 04 of 06
Week 7: OOP Principles & Design Patterns.
Week 7: Focus on object-oriented programming principles (encapsulation, inheritance, polymorphism, abstraction) and common design patterns (e.g., Singleton, Factory, Observer).
Phase 05 of 06
Weeks 8-9: Behavioral Interview Prep (STAR Method), Microsoft Culture.
Weeks 8-9: Prepare for behavioral interviews. Use the STAR method to structure answers for common questions about teamwork, challenges, failures, and successes. Research Microsoft's values and culture.
Phase 06 of 06
Week 10: Mock Interviews & Final Review.
Week 10: Mock interviews. Practice coding problems and system design scenarios under timed conditions. Get feedback from peers or mentors. Review areas where you need improvement.
