Technical Interview (Coding) · 45 min · Software Engineer

This round focuses on assessing your fundamental programming skills. You will be asked to solve coding problems that test your knowledge of data structures (arrays, linked lists, trees, graphs, hash maps) and algorithms (sorting, searching, dynamic programming, recursion). The interviewer will evaluate your approach to problem-solving, your ability to write clean and efficient code, and your understanding of time and space complexity.

What they look for

Strong understanding of data structures and algorithms.Ability to translate a problem into code.Logical thinking and systematic approach to problem-solving.Clean and efficient coding style.

Evaluation

  • Correctness of solution
  • Efficiency of solution (time and space complexity)
  • Code clarity and readability
  • Problem-solving approach

Sample questions

  • Given an array of integers, find the two numbers that add up to a specific target.
