Data Structures and Algorithms

This is the most important section. The interviewer will expect you to have good problem-solving skills and strong command of Data Structures and Algorithms for the role.

They may ask you advanced-level coding questions in the interview. Some of the topics that are important

  • Revise all traversals ( Zigzag, In, pre, post, level, etc)
  • Sum of all subarray of an array
  • Reverse linked list
  • Find whether a loop in linked list
  • Find whether there is a cycle in graph
  • Implement AVL trees.
  • Coin change problem.
  • Heap Sort
  • Graph coloring Problem
  • Shortest path in graph ( if u don’t know implementation just tell them theory, Prim’s, and Kruskal)
  • Insertion and deletion in BST ( U have to write code)
  • All views of the Binary search tree.
  • Knapsack Problem
  • Water Trapping Problem


The interviewer can ask questions from core cs subjects like DBMS, OOPS, OS, Software Engineering, and Computer Architecture. It is always recommended to prepare notes as these are theoretical subjects and preparing notes helps in last-minute revisions.

Have a look at Edyst Webinar on HackWithInfy (HWI) 2020. The webinar consists of Important concepts to prepare for HackWithInfy Coding Round.

Questions on your Projects

The interviewer can ask for approaches for the project. Like, how you got the idea to make a particular project, what problems did you face, and how you solved it. Always prepare your project very well and be honest with your resume because most of the questions asked are from your resume only.

Try to prepare your project in the latest technologies like Machine Learning, React, etc. This will have a positive impact on the interviewer as the role requires learning the latest technologies according to the requirements.

Prepare your Resume well and be specially prepared for questions related to your Project.

“BELIEVE in yourself, and hope for the best.”
