Phase 01 of 04

Data Structures and Algorithms

Weeks 1-2: Data Structures & Algorithms fundamentals. Practice 2-3 problems/day.

Weeks 1-2: Focus on core data structures (arrays, linked lists, trees, graphs, hash maps) and algorithms (sorting, searching, dynamic programming, graph traversal). Practice implementing these in your preferred language and analyze their time and space complexity. Aim for 2-3 coding problems per day.

Technical Coding Interview · 45 min · Software Engineer

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

What they look for

Correctness of the solution.Efficiency of the solution.Clarity of the code.Ability to explain the solution and its trade-offs.

Evaluation

  • Coding proficiency
  • Problem-solving approach
  • Understanding of time and space complexity
  • Ability to write clean, maintainable code

Sample questions

  • Given a list of car IDs and their booking dates, find the car with the most consecutive bookings.

    ArrayHash MapSliding Window
  • Implement a function to find the lowest common ancestor of two nodes in a binary tree.

    TreeRecursionBinary Search Tree
  • Given a string, find the length of the longest substring without repeating characters.
