Data Structures And Algorithms Interview · 60 min · Senior Software Engineer or Tech Lead

This round focuses on your core programming skills. You will be asked to solve one or two coding problems that test your knowledge of data structures and algorithms. The interviewer will assess your ability to write efficient, bug-free code and explain your approach.

What they look for

Strong grasp of fundamental algorithms and data structures.Ability to write clean, efficient, and well-structured code.Logical thinking and systematic approach to problem-solving.Communication of thought process during coding.

Evaluation

  • Correctness and efficiency of the solution.
  • Code quality and readability.
  • Understanding of time and space complexity.
  • Problem-solving approach and ability to handle follow-up questions.

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 ListPointers
  • Find the k-th smallest element in a binary search tree.

    TreeBinary Search TreeRecursion

Prep for this round
