In the beginning, I started learning about basics DSA concepts. These included topics like array, string, stack, queue and solving questions on hacker rank. After practising enough on Hacker Rank, I moved to advanced DSA topics including LinkedList, Tree, Graph, DP, etc. I practiced these topics on Geeksforgeeks, leetcode, codeforces. Then I gave some mock interviews as well that helped me prepare for interviews.

This was an on-campus opportunity. The company visited our campus and we directly applied through their portal. Shortlisting was done on the basis of resumes and then further interview rounds were carried out.

My basic concepts of all the topics were clear and I also prepared HR questions through mock interviews. I practised all the basic to medium coding question before interview.
