Technical Interview (Coding) · 45 min · Software Engineer (SDE 2/3)

This round focuses on assessing your core programming skills. You will be asked to solve one or two coding problems, typically involving data structures and algorithms. The interviewer will evaluate your ability to understand the problem, devise an efficient solution, write clean code, and explain your thought process. Be prepared to discuss time and space complexity.

What they look for

Strong problem-solving skills.Proficiency in a chosen programming language.Ability to write clean and efficient code.Understanding of time and space complexity.

Evaluation

  • Correctness of the solution
  • Efficiency of the solution (time and space complexity)
  • Code clarity and readability
  • Ability to explain the approach and reasoning

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 kth smallest element in a binary search tree.
