01 / 04Phase 01 of 04
Weeks 1-2: DSA fundamentals and practice (2-3 problems/day).
Weeks 1-2: Focus on Data Structures and Algorithms. Cover arrays, linked lists, trees, graphs, hash tables, heaps, sorting, searching, dynamic programming, and greedy algorithms. Practice implementing these and analyzing their time and space complexity. Aim for 2-3 coding problems per day.
Phase 02 of 04
Weeks 3-4: System Design principles and practice.
Weeks 3-4: Dive into System Design. Study concepts like scalability, availability, reliability, consistency, load balancing, caching, databases (SQL vs. NoSQL), message queues, and microservices architecture. Review common system design interview questions and practice designing systems like Twitter feed, URL shortener, or a distributed cache.
Phase 03 of 04
Week 5: Behavioral questions (STAR method) and company research.
Week 5: Prepare for Behavioral and Situational Questions. Reflect on your past experiences and identify examples that demonstrate leadership, teamwork, problem-solving, conflict resolution, and handling failure. Use the STAR method to structure your answers. Research Zoox's values and prepare to align your experiences with them.
Phase 04 of 04
Week 6: Mock interviews and final review.
Week 6: Mock Interviews and Refinement. Conduct mock interviews with peers or mentors to simulate the actual interview experience. Focus on improving communication, clarity of thought, and time management. Review any weak areas identified during practice and refine your answers.
