Technical Interview - Data Structures And Algorithms · 45 min · Software Engineer / Senior Software Engineer

This round focuses on your core computer science knowledge. You will be presented with one or two coding problems that require the application of data structures and algorithms. The interviewer will assess your ability to understand the problem, devise an efficient solution, write clean code, and explain your thought process. Expect to discuss time and space complexity and consider various edge cases.

What they look for

Strong grasp of fundamental data structures and algorithms.Logical and systematic problem-solving approach.Clean, efficient, and well-commented code.Ability to communicate technical ideas effectively.

Evaluation

  • Correctness of the solution.
  • Efficiency of the solution (time and space complexity).
  • Clarity and readability of the code.
  • Ability to explain the approach and trade-offs.
  • Handling of edge cases.

Sample questions

  • Given an array of integers, return indices of the two numbers such that they add up to a specific target.

    ArrayHash TableTwo Pointers

  • Reverse a linked list.

    Linked ListRecursionIteration

  • Implement a binary search tree and its common operations (insert, search, delete).

    TreeBinary Search TreeData Structures

  • Find the kth smallest element in a binary search tree.

    TreeBinary Search TreeRecursionIteration

Prep for this round

  1. 01Practice coding problems on platforms like LeetCode, HackerRank, or Coderbyte.
  2. 02Focus on understanding the underlying data structures and algorithms, not just memorizing solutions.
  3. 03Practice explaining your code and thought process out loud.
  4. 04Be prepared to write code on a whiteboard or in a shared editor.

Common rejection reasons

  • ×Inability to articulate thought process clearly.
  • ×Lack of fundamental understanding of data structures and algorithms.
  • ×Poor coding practices (e.g., unreadable code, no error handling).
  • ×Failure to consider edge cases or optimize solutions.
