Technical Interview (Data Structures & Algorithms) · 60 min · Senior Software Engineer or Tech Lead

This round focuses on assessing your core technical skills, particularly in data structures and algorithms. You will be presented with coding problems, and you'll need to write code to solve them, explaining your thought process and analyzing the complexity of your solution. Expect questions that test your understanding of arrays, strings, linked lists, trees, graphs, dynamic programming, and sorting/searching algorithms.

What they look for

Strong analytical and problem-solving skillsProficiency in codingUnderstanding of algorithms and data structuresAbility to think through edge cases and constraints

Evaluation

  • Correctness of the solution
  • Efficiency of the solution (time and space complexity)
  • Clarity and readability of the code
  • Problem-solving approach
  • Ability to handle edge cases

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.
