Data Structures and Algorithms Fundamentals

Weeks 1-2: Data Structures & Algorithms (Core)

Weeks 1-2: Focus on core data structures (Arrays, Linked Lists, Trees, Graphs, Hash Tables) and their common algorithms (Sorting, Searching, Traversal). Practice implementing these from scratch and analyze their time and space complexity. Cover basic dynamic programming problems.

Questions

Commonly asked.

  • Write a function to reverse a linked list.
  • Given an array of integers, find the two numbers that add up to a specific target.
  • Explain the difference between a process and a thread.
  • Describe a situation where you had to deal with a difficult stakeholder.
  • How would you design a URL shortening service?
  • What are the trade-offs between SQL and NoSQL databases?
  • Tell me about a time you failed and what you learned from it.
  • How do you stay updated with new technologies?

Technical Interview (Coding) · 45 min · Software Engineer (L4/L5)

This round focuses on assessing your core programming skills. You will be given one or two coding problems, typically involving data structures and algorithms. The interviewer will expect you to write clean, efficient, and correct code, and to clearly articulate your approach, discuss time/space complexity, and consider edge cases.

What they look for

Solid understanding of data structures and algorithms.Ability to translate a problem into code.Clear communication of thought process.Attention to detail in coding.

Evaluation

  • Correctness of the solution
  • Efficiency of the solution (time and space complexity)
  • Clarity and correctness of code
  • Ability to explain the approach and trade-offs

Sample questions

  • Given a binary tree, determine if it is a valid binary search tree.

    Data StructuresTreesRecursion

  • Find the kth smallest element in an unsorted array.
