Technical Coding Interview · 45 min · Software Engineer

This round focuses on assessing your core programming skills and problem-solving abilities. You will be asked to solve one or two coding problems, typically involving data structures and algorithms. The interviewer will evaluate your approach, the efficiency of your solution, and the quality of your code. Expect to write code in a shared editor and explain your thought process throughout.

What they look for

Strong grasp of fundamental data structures and algorithms.Ability to translate a problem into a working code solution.Clear communication of the approach and trade-offs.Attention to detail and ability to handle edge cases.

Evaluation

  • Correctness of the solution.
  • Efficiency of the solution (time and space complexity).
  • Code quality, readability, and maintainability.
  • Ability to communicate the thought process and justify the solution.
  • Handling of edge cases and error conditions.

Sample questions

  • Given an array of integers, find the contiguous subarray with the largest sum.

    ArrayDynamic Programming

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

Prep for this round

  1. 01Practice coding problems on platforms like LeetCode, HackerRank, or Coderbyte.
  2. 02Focus on understanding the underlying data structures and algorithms.
  3. 03Be prepared to discuss the time and space complexity of your solutions.
  4. 04Practice explaining your thought process clearly and concisely.
  5. 05Write clean, well-structured, and commented code.

Common rejection reasons

  • ×Lack of fundamental understanding of data structures and algorithms.
  • ×Inability to write clean, efficient, or bug-free code.
  • ×Poor time complexity analysis.
  • ×Difficulty in explaining the thought process.
  • ×Not meeting the minimum bar for coding proficiency.
