Data Structures And Algorithms Interview · 60 min · Senior Software Engineer

This round involves solving one or two coding problems, typically focused on data structures and algorithms. You'll be expected to write clean, efficient, and well-tested code. The interviewer will assess your problem-solving approach, your understanding of algorithmic complexity, and your ability to communicate your thought process while coding.

What they look for

Strong coding skills in at least one primary language.Ability to translate requirements into working code.Proficiency with common data structures and algorithms.Logical thinking and systematic approach to problem-solving.Ability to test and debug code effectively.

Evaluation

  • Correctness and efficiency of the code.
  • Understanding of time and space complexity.
  • Code readability, structure, and maintainability.
  • Problem-solving approach and ability to handle edge cases.

Sample questions

  • Given a binary tree, find the lowest common ancestor of two given nodes.

    Data StructuresAlgorithmsTrees
  • Implement a function to find the k-th largest element in an unsorted array.
