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

This round focuses on your core computer science fundamentals. You will be presented with one or two challenging algorithmic or data structure problems. The interviewer will assess your ability to understand the problem, devise an efficient solution, write clean and correct code, and analyze its time and space complexity. Expect follow-up questions to explore edge cases and potential optimizations.

What they look for

A systematic approach to problem-solving.Correct and efficient use of data structures and algorithms.Clean, well-structured, and bug-free code.Clear communication of the solution and trade-offs.

Evaluation

  • Problem-solving approach.
  • Algorithmic knowledge.
  • Data structure proficiency.
  • Code quality and efficiency.
  • Ability to explain thought process.

Sample questions

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

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

    ArraySortingHeapQuickSelect
  • Design and implement a data structure that supports adding new elements and retrieving the median of all elements in constant time.

    Data StructuresHeapTwo Pointers
  • Given a string containing just the characters '(', ')', '{', '}', '[' and ']', determine if the input string is valid.
