This was on-campus. There were 5 people in the room. 3 of the senior people interviewed me. As I entered and sat, I introduced myself (name and branch and that I was interning and where).
Followed by some light questions (to test your confidence I guess):
Q: What did you have for lunch? (I was the first to be interview post-lunch)
A: Sandwiches
Q: Why?
A: I wanted to have something light
Q: Why, are you nervous for the interview?
A: Both nervousness and excitement
Q: Which is more?
A: Excitement
