Fig · Study plan — 05 phases
01 / 05Phase 01 of 05
Weeks 1-2: Data Structures & Algorithms (DSA) fundamentals. Practice coding.
Weeks 1-2: Focus on core data structures (arrays, linked lists, trees, graphs, hash maps) and algorithms (sorting, searching, dynamic programming, recursion). Practice implementing these in your primary programming language. Review Big O notation for time and space complexity.
Phase 02 of 05
Weeks 3-4: Object-Oriented Programming & Design Patterns. Code quality.
Weeks 3-4: Deep dive into object-oriented programming (OOP) principles (encapsulation, inheritance, polymorphism, abstraction). Study design patterns (e.g., Singleton, Factory, Observer) and their applications. Practice writing clean, maintainable, and scalable code.
Phase 03 of 05
Weeks 5-6: System Design principles. Scalability & Architecture.
Weeks 5-6: Learn system design concepts. Focus on scalability, availability, reliability, and performance. Study topics like load balancing, caching, database design (SQL vs. NoSQL), message queues, and microservices architecture. Practice designing common systems (e.g., URL shortener, Twitter feed).
Phase 04 of 05
Week 7: Behavioral questions (STAR method) & Company Research.
Week 7: Prepare for behavioral and situational questions. Reflect on past experiences related to teamwork, problem-solving, leadership, and handling challenges. Use the STAR method to structure your answers. Research BNY Mellon's values and mission.
Phase 05 of 05
Week 8: Mock Interviews & Final Review. Prepare questions.
Week 8: Mock interviews with peers or mentors. Focus on articulating your thought process clearly and concisely. Review any areas you feel weak in. Prepare a list of insightful questions to ask the interviewers.
