Technical Interview (Coding) · 45 min · Software Engineer / Senior Software Engineer

This round focuses on your core programming skills. You will be asked to solve one or two coding problems, typically involving data structures and algorithms. The interviewer will assess your ability to write clean, efficient, and correct code, as well as your approach to problem-solving and your communication skills during the process.

What they look for

Strong grasp of fundamental computer science concepts.Ability to translate a problem into a working code solution.Clear communication of the thought process.Attention to detail and ability to consider edge cases.

Evaluation

  • Correctness of the solution.
  • Efficiency of the solution (time and space complexity).
  • Code quality and readability.
  • Problem-solving approach and thought process.
  • Ability to handle edge cases and constraints.

Sample questions

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

    ArrayDynamic ProgrammingAlgorithm

  • Implement a function to reverse a linked list.

    Linked ListPointersAlgorithm

  • Find the kth smallest element in a binary search tree.

    TreeBinary Search TreeAlgorithm

Prep for this round

  1. 01Practice coding on a whiteboard or a shared editor.
  2. 02Think out loud and explain your approach before coding.
  3. 03Test your code with sample inputs, including edge cases.
  4. 04Be prepared to discuss alternative solutions and their trade-offs.

Common rejection reasons

  • ×Inability to articulate thought process clearly.
  • ×Lack of fundamental understanding of data structures and algorithms.
  • ×Poor coding practices (e.g., unreadable code, no error handling).
  • ×Inability to optimize solutions for time or space complexity.
