Technical Coding Interview · 60 min · Software Engineer / Senior Software Engineer

This round focuses on your core programming skills and problem-solving abilities. You will be presented with one or two coding challenges, 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 tackling complex problems and communicating your thought process.

What they look for

Strong grasp of fundamental CS concepts.Ability to translate requirements into working code.Problem-solving skills and logical thinking.Attention to detail and edge case handling.Clear communication of approach.

Evaluation

  • Correctness of the solution.
  • Efficiency of the algorithm (time and space complexity).
  • Code clarity, style, and maintainability.
  • Ability to test the code and handle edge cases.
  • Communication of the thought process.

Sample questions

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