Mostly, interviewers asked:

1. 1-2 DSA questions, where the candidate had to write code on paper and explain their approach and time complexity.
2. Questions about almost every detail on the resume. The advice was to know everything written on the resume thoroughly and be honest.

Interview Round 2 (Technical + HR):

After successfully completing the first technical round, the candidate proceeded to this round, which was a mix of technical and HR questions and lasted 40-50 minutes. The interviewer was very friendly, and the interview started with a formal discussion about the candidate.

Questions were asked about projects, requiring detailed explanations including:

The interviewer also asked about OOPs (C++) concepts, ranging from the four pillars of OOP in C++ to polymorphism and virtual functions. Lastly, there were a few behavioral questions.

After all rounds, 4 students were selected. The candidate emphasized knowing everything on the resume thoroughly for confidence.
