Weird IIT Roorkee PI experience.

Entered the panel, gave some introduction and a panelist did some cross questioning of my startup while the other panelist barely maintained eye contact. And that's it, my interview was done 🙃 Ended in 5-6 minutes

What's your opinion about this? Is it a straight reject? They were bored with me? They didn't want another engineering fresher in their batch? Or is it normal?
