Technical Interview - Coding · 45 min · 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 understand the problem, devise a solution, write clean code, and analyze its efficiency. Expect follow-up questions to explore edge cases and potential optimizations.

What they look for

A clear and logical approach to problem-solving.Proficiency in writing clean, efficient, and bug-free code.Understanding of time and space complexity.Ability to communicate thought process effectively.Willingness to consider alternative solutions and optimizations.

Evaluation

  • Correctness of the solution
  • Efficiency of the solution (time and space complexity)
  • Code quality and readability
  • Problem-solving approach
  • Ability to handle follow-up questions and optimizations

Sample questions

  • Given a binary tree, find its inorder traversal.

    TreeRecursionIteration

  • Find the kth smallest element in a sorted matrix.

    MatrixBinary SearchHeap

Prep for this round

  1. 01Practice coding problems on platforms like LeetCode, focusing on medium difficulty.
  2. 02Ensure you can explain your thought process while coding.
  3. 03Be prepared to discuss the time and space complexity of your solutions.
