Distributed Systems & Architecture
Weeks 1-2: Distributed Systems Fundamentals & Design Patterns.
Weeks 1-2: Deep dive into distributed systems concepts, including consensus algorithms (Paxos, Raft), CAP theorem, microservices architecture, message queues, and caching strategies. Review common system design patterns and anti-patterns. Focus on understanding trade-offs in various design choices.
Scalability & Data Engineering
Weeks 3-4: Scalability, Data Systems & Performance.
Weeks 3-4: Focus on large-scale data processing, database technologies (SQL vs. NoSQL, sharding, replication), and performance optimization techniques. Explore cloud computing platforms (AWS, Azure, GCP) and their services relevant to building scalable applications.
Leadership & Behavioral Skills
Weeks 5-6: Behavioral & Leadership Preparation.
Weeks 5-6: Prepare for behavioral and leadership questions. Reflect on your career experiences, focusing on instances of technical leadership, mentorship, conflict resolution, and influencing others. Practice articulating these experiences using the STAR method (Situation, Task, Action, Result).
Practice & Feedback
Week 7: Mock Interviews & Refinement.
Week 7: Conduct mock interviews with peers or mentors, focusing on system design and behavioral questions. Seek feedback on your communication, problem-solving approach, and clarity of thought. Refine your answers and identify areas for improvement.
Final Preparation
Week 8: Final Review & Research.
Week 8: Final review of all topics. Research recent LinkedIn engineering blogs and technical talks to understand current challenges and innovations. Prepare thoughtful questions for the interviewers.
