Weeks 3-4: Dive into system design. Study common design patterns, database choices, caching strategies, load balancing, and message queues. Work through system design case studies and practice designing scalable systems like Twitter feed, URL shortener, or a distributed cache.
Distributed Systems
Week 5: Distributed Systems Concepts. Understand CAP theorem and consensus.
Week 5: Focus on distributed systems concepts. Understand CAP theorem, consensus algorithms (Paxos, Raft), replication, sharding, and fault tolerance. Read relevant papers and articles on distributed systems.
Networking and Protocols
Week 6: Networking & Protocol Fundamentals. Review TCP/IP, HTTP, DNS.
Week 6: Review networking fundamentals (TCP/IP, HTTP, DNS) and common protocols used in networking infrastructure. If the role is hardware-focused, study embedded systems and real-time concepts.
Behavioral Preparation
Week 7: Behavioral Interview Prep. Use STAR method for past experiences.
Week 7: Prepare for behavioral interviews. Reflect on your past projects and experiences. Use the STAR method (Situation, Task, Action, Result) to structure your answers for questions about teamwork, leadership, conflict resolution, and handling failures.
Mock Interviews and Refinement
Week 8: Mock Interviews & Refinement. Practice with peers and get feedback.
Week 8: Mock interviews. Conduct mock interviews with peers or mentors to simulate the actual interview environment. Get feedback on your technical explanations, problem-solving approach, and communication skills. Refine your answers and identify areas for improvement.
