Study Plan

1

Data Structures and Algorithms

Weeks 1-2: Data Structures & Algorithms fundamentals. Practice coding.

Weeks 1-2: Focus on core data structures (arrays, linked lists, trees, graphs, hash maps) and algorithms (sorting, searching, dynamic programming, graph traversal). Practice implementing these in your preferred language. Aim for at least 5-10 problems per data structure/algorithm type.

2

System Design

Weeks 3-4: System Design principles and practice.

Weeks 3-4: Dive into system design principles. Cover topics like scalability, availability, reliability, databases (SQL vs. NoSQL), caching, load balancing, and API design. Study common system design interview questions and practice designing systems like Twitter feed or URL shortener.

3

Behavioral and Cultural Fit

Week 5: Behavioral preparation using STAR method and company research.

Week 5: Prepare for behavioral interviews. Identify key projects from your past experience and frame them using the STAR method (Situation, Task, Action, Result). Think about examples that demonstrate teamwork, problem-solving, leadership, and handling failure. Also, research Cruise's values and mission.

4

Mock Interviews and Final Review

Week 6: Mock interviews and final review.

Week 6: Mock interviews and final review. Conduct mock interviews with peers or mentors to simulate the actual interview environment. Review any weak areas identified during practice and solidify your understanding of key concepts.
