21 students were selected after this round.

Technical Round 1  (Duration: 1hr): This round was Data Structures and Algorithms round. Two questions asked by the interviewer were – 

1. Finding Loop in Linked List (Tortoise and Hare Method) (Medium)
2. Find k largest elements of an array (Heaps) (Easy/Medium)

10-12 students were selected for Round 2.

Technical Round 2 (Duration: 1hr): This round was mainly about projects and Computer Science Fundamentals. First, the interviewer asked me to explain my project and asked some related questions. They asked me about authentication, authorization, the need for authentication, and the ways it can be implemented (Sessions and JWT Tokens). 

Next, they asked DBMS-related questions:
