01 / 04Phase 01 of 04
Weeks 1-2: Data Structures & Algorithms (Medium/Hard LeetCode).
Weeks 1-2: Focus on core data structures and algorithms. Review common algorithms (sorting, searching, graph traversal) and data structures (arrays, linked lists, trees, hash maps). Practice coding problems on platforms like LeetCode, HackerRank, focusing on medium to hard difficulty. Understand time and space complexity analysis.
Phase 02 of 04
Weeks 3-4: System Design Fundamentals & Practice.
Weeks 3-4: Deep dive into system design principles. Study topics like scalability, availability, consistency, load balancing, caching, databases (SQL vs. NoSQL), message queues, and microservices architecture. Read system design case studies and practice designing common systems (e.g., Twitter feed, URL shortener).
Phase 03 of 04
Week 5: Behavioral & Leadership Preparation (STAR Method).
Week 5: Prepare for behavioral and leadership questions. Reflect on your past experiences and identify examples that demonstrate leadership, problem-solving, teamwork, and conflict resolution. Use the STAR method to structure your answers. Understand Workday's values and how your experiences align.
Phase 04 of 04
Week 6: Technology Review & Question Preparation.
Week 6: Review specific technologies relevant to the role (e.g., cloud platforms like AWS/Azure/GCP, specific programming languages like Java/Python/C++, databases, CI/CD tools). Understand Workday's tech stack if possible. Prepare questions for the interviewers about the role, team, and company.
