It was a hobnob cum interview, very informal and interesting. The founders themselves took the interview. Firstly they asked general things like about yourself, interests, what interests you to do internship in this field etc.etc. Then they asked about our previous experiences and participations, if any. Also we were asked about the what we actually feel about the concerned industry. It wasn't a technical interview at all, they were just looking for one thing that is are we culturally fit to that startup environment that's it. All in all it was an awesome experience.
