Technical Interview (Coding) · 45 min · Software Engineer

This round focuses on your core technical 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 an efficient solution, write clean and correct code, and explain your reasoning throughout the process. Expect to discuss time and space complexity.

What they look for

Solid understanding of data structures and algorithms.Ability to translate a problem into working code.Clear communication of thought process.Attention to edge cases and error handling.

Evaluation

  • Correctness of the solution
  • Efficiency of the solution (time and space complexity)
  • Code clarity and readability
  • Ability to test the code
  • Problem-solving approach

Sample questions

  • Given a string, find the length of the longest substring without repeating characters.

    StringSliding WindowHash Map

  • Implement a function to check if a binary tree is a Binary Search Tree (BST).
