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

This round focuses on your fundamental programming skills. You will be presented with 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, write clean and correct code, and analyze its performance. Expect to discuss trade-offs and alternative approaches.

What they look for

Strong grasp of data structures and algorithms.Ability to translate requirements into working code.Systematic approach to problem-solving.Attention to detail and edge case handling.Clear communication of thought process.

Evaluation

  • Correctness and efficiency of the solution.
  • Clarity and organization of the code.
  • Ability to analyze time and space complexity.
  • Problem-solving approach and adaptability.
  • Communication of the solution.

Sample questions

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

    Data StructuresTreesAlgorithms

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

    ArraysSortingAlgorithms

  • Design a data structure that supports insert, delete, search, and getRandom in O(1) average time.
