Big Worldwide interview questions

A few months ago I had few interviews with people from Just Meet Digital Events (which apparently is a part of Big Worldwide that they were constantly reminding), and I was just feeling sorry for myself to completely waste my time. The man who I believe is the Head of marketing was extremely unprofessional. He was asking me private questions and put himself in a 'the cool man' role instead of a potential employer. To this day I don't even know if it wasn't a scam because he disappeared.
