Data Structures and Algorithms

Weeks 1-2: Data Structures & Algorithms fundamentals. Practice 2-3 problems/day.

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. Aim for 2-3 coding problems per day.

Technical Interview - Coding · 45 min · Software Engineer

This round focuses on your fundamental programming skills. You will be asked to solve one or two coding problems that test your knowledge of data structures (e.g., arrays, linked lists, trees, hash maps) and algorithms (e.g., sorting, searching, dynamic programming). The interviewer will assess your ability to write clean, efficient, and correct code, as well as your approach to problem-solving and communicating your thought process.

What they look for

Strong understanding of data structures and algorithms.Ability to translate a problem into clean, efficient code.Clear communication of thought process.Attention to detail and edge case handling.

Evaluation

  • Correctness of the solution
  • Efficiency of the solution (time and space complexity)
  • Code clarity and readability
  • Problem-solving approach
  • Ability to handle edge cases

Sample questions

  • Given a binary tree, invert the tree.

    TreeRecursionData Structures

  • Find the kth largest element in an unsorted array.

    ArraySortingQuickSelectData Structures

Prep for this round

  1. 01Practice coding problems on platforms like LeetCode, focusing on medium difficulty.
  2. 02Review common data structures and algorithms.
  3. 03Practice explaining your solution out loud as you code.
  4. 04Be prepared to discuss time and space complexity.

Common rejection reasons

  • ×Inability to articulate thought process clearly.
  • ×Lack of fundamental data structures and algorithms knowledge.
  • ×Poor coding practices (e.g., inefficient solutions, unreadable code).
