Data Structures & Algorithms
Weeks 1-2: DSA fundamentals and practice (medium-hard LeetCode).
Weeks 1-2: Focus on Data Structures and Algorithms. Review fundamental data structures (arrays, linked lists, trees, graphs, hash maps) and algorithms (sorting, searching, dynamic programming, graph traversal). Practice solving problems on platforms like LeetCode, HackerRank, or AlgoExpert, aiming for medium to hard difficulty problems. Pay attention to time and space complexity analysis.
System Design
Weeks 3-4: System Design principles and practice (scalability, databases, distributed systems).
Weeks 3-4: Deep dive into System Design. Study concepts like scalability, load balancing, caching, database design (SQL vs. NoSQL), message queues, and distributed systems. Read resources like 'Designing Data-Intensive Applications' and 'System Design Interview – An insider's guide'. Practice designing common systems (e.g., Twitter feed, URL shortener, e-commerce platform).
Behavioral & Leadership
Week 5: Behavioral questions (STAR method) and Adobe values alignment.
Week 5: Behavioral and Leadership Preparation. Reflect on your past experiences and prepare stories using the STAR method for common behavioral questions related to leadership, teamwork, conflict resolution, failure, and success. Understand Adobe's values and how your experiences align with them.
Mock Interviews & Refinement
Week 6: Mock interviews and feedback for refinement.
Week 6: Mock Interviews and Refinement. Conduct mock interviews with peers or mentors, focusing on both technical and behavioral aspects. Get feedback on your communication, problem-solving approach, and overall presentation. Refine your answers and strategies based on the feedback.
