01 / 04Phase 01 of 04
Weeks 1-2: Data Structures & Basic Algorithms. Practice implementations and problem-solving.
Weeks 1-2: Focus on core data structures (Arrays, Linked Lists, Stacks, Queues, Trees, Graphs, Hash Maps) and their common operations and time complexities. Practice implementing these structures and solving problems involving them. Review basic algorithms like sorting (Merge Sort, Quick Sort) and searching (Binary Search).
Phase 02 of 04
Weeks 3-4: Advanced Algorithms & Problem Solving. Focus on DP, recursion, graphs. Practice medium LeetCode.
Weeks 3-4: Deep dive into algorithmic techniques such as recursion, dynamic programming, greedy algorithms, and graph traversal (BFS, DFS). Work on problems that require applying these techniques. Start practicing medium-level LeetCode problems.
Phase 03 of 04
Week 5: Behavioral Preparation. STAR method, resume review, company values.
Week 5: Prepare for behavioral interviews. Review your resume and identify key projects and experiences. Practice articulating your contributions using the STAR method. Research Snowflake's values and prepare examples that demonstrate alignment.
Phase 04 of 04
Week 6: System Design Basics & Mock Interviews. Practice overall interview flow.
Week 6: Focus on system design fundamentals, even for an IC1 role. Understand concepts like scalability, availability, and basic database design. Review common interview questions related to these topics. Practice mock interviews, both technical and behavioral.
