Preparation

How to prepare.

Tips

  1. Review fundamental data structures (arrays, linked lists, trees, graphs, hash maps) and algorithms (sorting, searching, dynamic programming).
  2. Practice coding problems on platforms like LeetCode, HackerRank, or Coderbyte, focusing on easy and medium difficulty.
  3. Understand basic object-oriented programming (OOP) principles.
  4. Familiarize yourself with common software development tools and methodologies (e.g., Git, Agile).
  5. Prepare to discuss your past projects and experiences in detail.
  6. Research Compass's mission, values, and recent projects.
  7. Practice answering behavioral questions using the STAR method (Situation, Task, Action, Result).

Data Structures Fundamentals

Weeks 1-2: Data Structures (Arrays, Linked Lists, Stacks, Queues, Hash Maps) & Big O.

Weeks 1-2: Focus on core data structures like arrays, linked lists, stacks, queues, and hash maps. Practice problems involving these structures. Understand time and space complexity analysis (Big O notation).

Questions

Commonly asked.

  • Write a function to reverse a linked list.
  • Given an array of integers, find the two numbers that add up to a specific target.
