Data Structures And Algorithms Interview · 60 min · Software Engineer (Peer)

This round focuses on your fundamental computer science knowledge. You will be presented with one or two coding problems that require you to implement algorithms and use appropriate data structures. The interviewer will assess your ability to write clean, efficient, and correct code, as well as your approach to problem-solving and debugging.

What they look for

Strong grasp of algorithms and data structures.Ability to translate a problem into efficient code.Clear communication of thought process.Attention to detail.

Evaluation

  • Correctness of the solution
  • Efficiency of the solution (time and space complexity)
  • Code clarity and maintainability
  • Ability to handle edge cases and constraints
  • Problem-solving approach

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 and implement a data structure that supports adding and retrieving elements in a specific order.
