Study plan
Fig · Study plan — 05 phases
01 / 05Phase 01 of 05
Weeks 1-2: Data Structures & Algorithms (Easy/Medium). Focus on implementation and complexity analysis.
Weeks 1-2: Focus on core data structures (arrays, linked lists, trees, graphs, hash tables) and algorithms (sorting, searching, dynamic programming, graph traversal). Practice implementing these in your preferred language and analyze their time and space complexity. Solve problems on platforms like LeetCode (Easy/Medium).
Phase 02 of 05
Weeks 3-4: Advanced Algorithms (Medium/Hard) & Operating Systems basics.
Weeks 3-4: Deep dive into advanced algorithms and complexity analysis. Cover topics like greedy algorithms, divide and conquer, and graph algorithms in more detail. Practice harder LeetCode problems (Medium/Hard). Begin exploring operating systems concepts (processes, threads, memory management, concurrency).
Phase 03 of 05
Weeks 5-6: System Design principles, distributed systems, databases, caching.
Weeks 5-6: Focus on system design. Study common design patterns, scalability principles, database design (SQL vs. NoSQL, trade-offs), caching strategies, load balancing, and message queues. Review distributed systems concepts like CAP theorem, consistency models, and consensus algorithms. Practice designing systems for common scenarios.
Phase 04 of 05
Weeks 7-8: Networking, Concurrency, Performance Optimization, Project Deep Dive, Behavioral Prep.
Weeks 7-8: Refine your understanding of networking protocols (TCP/IP, HTTP), concurrency control, and performance optimization techniques. Review your past projects and prepare detailed explanations, focusing on technical challenges, solutions, and impact. Practice behavioral questions and prepare specific examples using the STAR method.
Phase 05 of 05
Week 9: Mock Interviews, DRW Research, Question Preparation.
Week 9: Mock interviews focusing on coding, system design, and behavioral aspects. Get feedback and identify areas for improvement. Research DRW thoroughly, including their business, recent news, and technology stack. Prepare thoughtful questions to ask the interviewers.

Data Structures And Algorithms Interview · 45 min · Senior Software Engineer or Staff Engineer
This round focuses on your core computer science knowledge. You will be presented with one or two coding problems that require you to implement solutions using appropriate data structures and algorithms. The interviewer will assess your ability to analyze the problem, devise an efficient solution, write clean and correct code, and discuss the time and space complexity of your approach. Expect follow-up questions to test your understanding of edge cases and potential optimizations.

System Design Interview · 60 min · Senior Software Engineer or Architect
This round evaluates your ability to design complex software systems. You'll be given an open-ended problem (e.g., design a social media feed, a ride-sharing service, or a real-time analytics platform). The interviewer will expect you to clarify requirements, propose a high-level architecture, dive deep into specific components, discuss data models, APIs, scalability strategies, and potential bottlenecks. You should be prepared to justify your design decisions and discuss trade-offs.
