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

This round focuses on assessing your core computer science knowledge and problem-solving abilities. You will be presented with coding challenges that require you to implement algorithms and data structures. 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 problem-solving skills.Proficiency in coding and debugging.Understanding of algorithmic complexity.Ability to translate requirements into working code.

Evaluation

  • Correctness of the algorithm.
  • Efficiency of the solution (time and space complexity).
  • Clarity and correctness of code implementation.
  • Ability to handle edge cases and constraints.
  • Communication of thought process.

Sample questions

  • Given an array of integers, find the contiguous subarray with the largest sum.

    ArrayDynamic Programming
  • Implement a function to find the k-th smallest element in a binary search tree.

    TreeBinary Search TreeRecursion
  • Design and implement a basic LRU cache.
