01 / 04Phase 01 of 04
Weeks 1-2: Advanced DSA practice (LeetCode Hard). 2-3 hrs/day.
Weeks 1-2: Focus on advanced data structures (e.g., skip lists, B-trees, hash maps with collision resolution) and algorithms (e.g., dynamic programming, graph algorithms, greedy algorithms). Practice problems on platforms like LeetCode (Hard difficulty) and HackerRank. Aim for 2-3 hours of study per day.
Phase 02 of 04
Weeks 3-5: Distributed Systems theory & case studies. Read papers.
Weeks 3-5: Immerse yourself in distributed systems concepts. Read relevant papers (e.g., Google's MapReduce, Spanner, Dynamo), study topics like CAP theorem, eventual consistency, consensus algorithms (Paxos, Raft), load balancing, caching strategies, and message queues. Work through system design case studies.
Phase 03 of 04
Weeks 6-7: System Design practice (large-scale systems). Mock interviews.
Weeks 6-7: Focus on system design. Practice designing large-scale systems like Twitter feed, URL shortener, distributed cache, etc. Emphasize identifying requirements, defining APIs, data modeling, scaling strategies, fault tolerance, and trade-offs. Mock interviews are crucial here.
Phase 04 of 04
Week 8: Behavioral & Leadership prep (STAR method). Google values.
Week 8: Prepare for behavioral and leadership questions. Reflect on your career experiences, focusing on situations demonstrating leadership, conflict resolution, mentorship, and impact. Use the STAR method (Situation, Task, Action, Result) to structure your answers. Review Google's values.
