Study Plan

1

Data Structures and Algorithms

Weeks 1-2: Data Structures & Algorithms fundamentals. Practice implementations and complexity analysis.

Weeks 1-2: Focus on core data structures (arrays, linked lists, trees, graphs, hash maps) and algorithms (sorting, searching, dynamic programming, recursion). Practice implementing these from scratch and analyze their time and space complexity. Cover fundamental programming concepts in your primary language.

2

System Design Fundamentals

Weeks 3-4: System Design basics. Focus on components, scalability, and databases.

Weeks 3-4: Dive into system design basics. Understand concepts like scalability, availability, databases (SQL vs. NoSQL), caching, and APIs. For a Software Engineer I, focus on understanding the components and how they interact rather than designing complex distributed systems.

3

Behavioral Preparation

Week 5: Behavioral preparation using STAR method. Research company culture.

Week 5: Prepare for behavioral questions. Reflect on your past experiences using the STAR method (Situation, Task, Action, Result). Think about examples related to teamwork, problem-solving, handling failure, and learning new things. Also, research Harness's company culture and values.
