Hard

Technical Interview (Coding) · 60 min · Software Engineer / Senior Software Engineer

This round focuses on assessing your core programming skills. You will be asked to solve one or two coding problems, typically involving data structures and algorithms. The interviewer will evaluate your ability to understand the problem, devise an efficient solution, write clean and maintainable code, and explain your thought process. Expect questions that test your knowledge of arrays, strings, trees, graphs, dynamic programming, and sorting/searching algorithms.

What they look for

Strong grasp of fundamental algorithms and data structures.Ability to translate requirements into working code.Efficient and optimized solutions.Clear explanation of the approach.

Evaluation

  • Correctness of the solution.
  • Efficiency of the code (time and space complexity).
  • Code quality and readability.
  • Problem-solving approach.
  • Ability to communicate thought process.

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
  • Given a string s and a dictionary of strings wordDict, return true if s can be segmented into a space-separated sequence of one or more dictionary words.
