This round focuses on your fundamental programming skills. You will be asked to solve 1-2 coding problems that test your knowledge of data structures and algorithms. The interviewer will assess your ability to analyze the problem, devise an efficient solution, write clean code, and explain your reasoning.

What they look for

Strong grasp of data structures and algorithms.Ability to translate a problem into code.Logical thinking and systematic approach.Clean and readable code.

Evaluation

  • Correctness of the solution
  • Efficiency of the solution (time and space complexity)
  • Clarity and organization of the code
  • Problem-solving approach
  • Communication of the thought process

Sample questions

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

    ArrayHash Table
  • Reverse a linked list.

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