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

This round focuses on your fundamental computer science knowledge. You will be asked to solve coding problems, typically involving data structures and algorithms. The interviewer will assess your ability to analyze problems, devise efficient solutions, write clean code, and explain your thought process clearly. Expect questions on arrays, strings, linked lists, trees, graphs, dynamic programming, and sorting/searching algorithms.

What they look for

Strong grasp of algorithms and data structuresAbility to translate requirements into codeProblem-solving skillsClean and efficient code

Evaluation

  • Correctness of the solution
  • Efficiency of the solution (time and space complexity)
  • Clarity of explanation
  • Ability to handle edge cases
  • Coding style and best practices

Sample questions

  • Given an array of integers, find the contiguous subarray with the largest sum.

    ArrayDynamic Programming

  • Implement a function to reverse a linked list.

    Linked List

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

    TreeBinary Search TreeRecursion

  • Given two strings, determine if one is an anagram of the other.
