Technical Screening (Coding) · 45 min · Technical Screener / Software Engineer

This initial round typically involves a coding challenge, often conducted via a shared online editor. The interviewer will assess your ability to translate a problem statement into working code, focusing on algorithmic efficiency and code quality. You'll be expected to explain your approach and discuss trade-offs.

What they look for

A clear and logical approach to problem-solving.Proficiency in a chosen programming language.Understanding of fundamental data structures and algorithms.Ability to write clean, maintainable code.

Evaluation

  • Correctness of the solution
  • Efficiency (time and space complexity)
  • Code clarity and readability
  • Ability to handle edge cases
  • 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 reverse a linked list.

Prep for this round

  1. 01Practice coding problems under timed conditions.
  2. 02Be prepared to explain your code line by line.
  3. 03Think out loud and communicate your thought process.
  4. 04Ask clarifying questions if the problem statement is unclear.

Common rejection reasons

  • ×Inability to articulate thought process
  • ×Incorrect or inefficient algorithmic solutions
  • ×Poor coding practices (e.g., lack of comments, poor variable naming)
  • ×Not handling edge cases
