Aptitude

Prepare Aptitude from R.S Agarwal book which is more than enough to clear the Aptitude / MCQ Round.

Programming

Learn programming in your preferred Language (Java is Preferred by most of the employees). You can take an Udemy course to learn the basics of Java or Python3. While learning programming doesn’t forget to cover the Oops Concepts that are mostly asked in all the technical rounds of the interview.

  • Once you are good at Programming, start practicing problem solving along with the below sections. Try to solve 5 questions daily from Hacker Rank. It will make you feel confident while doing any kind of problem later. Initially it might take more time for solving the problems but your speed gets increased day by day.

Data Structures and Algorithms

For a fresher, the company evaluates him/her based on his coding and logical ability. They need us to think out-of-the-box and they don’t ask for miracles at the beginning itself. So you need to be strong at Data Structures and Algorithms which play a huge role in the whole interview process.

  • Start learning all Data Structures by yourself for free in Geeks for Geeks web material here. Most of the companies ask you to know Arrays, Linked List, Stack, Queue, Binary Tree Data Structures. If you want to get into a good MNC then you need to prepare Binary Search Tree, Heap, Hashing, Graph, Matrix, and Misc Data Structures along with them.
  • Learn Searching, Sorting, Greedy Algorithms as they are asked by most of the companies and similarly the advanced algorithms like Dynamic Programming, Back Tracking etc. are asked by the high paid companies. You can learn Algorithms from the Geeks for Geeks web material here
  • The DSA Course Offered by Geeks for Geeks helps a lot in understanding DSA in-depth if you code in Java or C++. (Note: This is not any promotion and comes out of my personal experience)
  • After completing the complete DSA, You need to evaluate your-self what you have learnt and are you able to solve the problems that are asked in interviews? You will know it by solving the most asked questions in top MNC’s from here
