Technical Interview - Data Structures & Algorithms · 45 min · Software Engineer

This round focuses on your fundamental programming skills. You will be asked to solve coding problems that test your knowledge of data structures and algorithms. The interviewer will assess your ability to analyze problems, devise efficient solutions, and write clean, well-structured code. Expect questions on arrays, strings, linked lists, trees, graphs, sorting, searching, and dynamic programming.

What they look for

Strong understanding of data structures and algorithms.Ability to translate a problem into a working code solution.Clear communication of thought process.Attention to detail in coding.

Evaluation

  • Problem-solving approach
  • Correctness of the solution
  • Efficiency of the solution (time and space complexity)
  • Code clarity and organization

Sample questions

  • Given an array of integers, find two numbers such that they add up to a specific target number.

    ArrayHash Table
  • Reverse a linked list.

    Linked List
  • Implement a function to check if a binary tree is a Binary Search Tree (BST).

    TreeRecursion
  • Find the kth smallest element in an unsorted array.
