Data Structures Fundamentals
Weeks 1-2: Data Structures & Complexity Analysis. Practice implementations and basic problems.
Weeks 1-2: Focus on core Data Structures (Arrays, Linked Lists, Stacks, Queues, Trees, Graphs, Hash Maps) and their common operations. Practice implementing these structures and solving problems related to them. Understand time and space complexity analysis (Big O notation).
Algorithm Mastery
Weeks 3-4: Algorithms (Sorting, Searching, DP, Graphs). Solve problems and optimize.
Weeks 3-4: Dive into Algorithms (Sorting, Searching, Dynamic Programming, Greedy Algorithms, Graph Traversal). Solve a variety of problems on coding platforms, categorizing them by algorithm type. Focus on optimizing solutions.
System Design Principles
Week 5: System Design. Study core concepts and practice designing systems.
Week 5: Concentrate on System Design. Study concepts like scalability, load balancing, caching, databases (SQL vs. NoSQL), message queues, and microservices. Practice designing common systems like URL shorteners, social media feeds, or e-commerce platforms.
OOP, Behavioral & Company Research
Week 6: OOP, Design Patterns, Behavioral Prep, Company Research.
Week 6: Review Object-Oriented Programming (OOP) concepts, design patterns, and best practices. Prepare for behavioral questions by identifying relevant experiences and structuring them using the STAR method. Research Virtusa.
Final Review & Practice
Week 7: Mock Interviews, Timed Coding Practice, Review.
Week 7: Mock interviews, practice coding under timed conditions, and refine explanations of technical concepts and past projects. Review weak areas identified during practice.
