Study Plan

1

Data Structures and Algorithms Fundamentals

Weeks 1-2: Data Structures (Arrays, Lists, Trees, Hash Maps) & Basic Algorithms (Sorting, Searching).

Weeks 1-2: Focus on core data structures like arrays, linked lists, stacks, queues, trees (binary trees, BSTs), and hash maps. Practice implementing them and solving problems involving their use. Review basic sorting and searching algorithms.

2

Algorithmic Thinking

Weeks 3-4: Advanced Algorithms (Recursion, DP, Graphs) & Complexity Analysis.

Weeks 3-4: Deep dive into algorithmic concepts such as recursion, dynamic programming, graph traversal (BFS, DFS), and complexity analysis (Big O notation). Practice medium-level problems on these topics.

3

Behavioral Preparation and Company Research

Week 5: Behavioral Questions (STAR Method) & Company Research.

Week 5: Prepare for behavioral questions. Understand the STAR method and prepare specific examples from your academic or project experience that demonstrate teamwork, problem-solving, and learning. Research Squarespace's culture and values.

4

Practice and Refinement

Week 6: Mock Interviews & Weakness Review.

Week 6: Mock interviews. Practice coding problems under timed conditions and simulate the interview environment. Get feedback from peers or mentors if possible. Review any weak areas identified during practice.
