Technical Interview (Coding) · 45 min · Software Engineer

This round is a technical screening focused on your core computer science knowledge. You will be asked to solve coding problems that test your understanding of data structures (like arrays, linked lists, trees, hash maps) and algorithms (like sorting, searching, graph traversal). The interviewer will assess your ability to write code, analyze its complexity, and explain your thought process.

What they look for

Strong understanding of data structures and algorithms.Ability to write clean, efficient, and bug-free code.Problem-solving skills and logical thinking.Communication of technical ideas.

Evaluation

  • Correctness of the solution.
  • Efficiency of the algorithm (time and space complexity).
  • Clarity and readability of the code.
  • Ability to explain the approach and trade-offs.

Sample questions

  • Given a binary tree, find its inorder traversal.

    Data StructuresTreesRecursion

  • Implement a function to find the kth smallest element in an unsorted array.

    AlgorithmsSortingQuickSelect

  • Write a function to check if a string is a palindrome, ignoring non-alphanumeric characters.

    StringsTwo Pointers

Prep for this round

  1. 01Practice coding problems on platforms like LeetCode, focusing on medium-difficulty questions.
  2. 02Review common data structures and algorithms and their use cases.
  3. 03Be prepared to explain your code and its time/space complexity.
  4. 04Practice thinking out loud as you solve problems.

Common rejection reasons

  • ×Inability to articulate thought process clearly.
  • ×Lack of fundamental data structure and algorithm knowledge.
  • ×Poor coding practices (e.g., unreadable code, inefficient solutions).
