Data Structures And Algorithms Interview · 45 min · Software Engineer (Peer)

This round focuses on your fundamental computer science knowledge. You will be asked to solve coding problems that test your understanding of data structures (like arrays, linked lists, trees, graphs, hash maps) and algorithms (like sorting, searching, dynamic programming). The interviewer will assess your ability to analyze the problem, choose appropriate data structures and algorithms, write clean code, and explain your thought process.

What they look for

Strong grasp of data structures and algorithms.Ability to write clean, efficient, and bug-free code.Logical thinking and problem-solving skills.Clear communication of thought process.

Evaluation

  • Correctness of the solution
  • Efficiency (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.

    Data StructuresTreesRecursion
  • Find the kth largest element in an unsorted array.

    AlgorithmsSortingHeaps
  • Implement a function to check if a string is a palindrome.
