Data Structures And Algorithms Interview · 45 min · Software Engineer / Senior 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 an efficient solution, and implement it correctly in code. They will also evaluate your thought process, communication during problem-solving, and how you handle edge cases and constraints.

What they look for

Strong grasp of fundamental algorithms and data structures.Ability to write clean, efficient, and bug-free code.Logical thinking and systematic approach to problem-solving.Understanding of time and space complexity.

Evaluation

  • Correctness of the solution.
  • Efficiency of the solution (time and space complexity).
  • Code quality, readability, and maintainability.
  • Problem-solving approach and ability to break down problems.

Sample questions

  • Given an array of integers, return indices of the two numbers such that they add up to a specific target.
