Growth Concepts interview questions

I was emailed about setting a 15 minute slot to Skype with David Whippe and presumably review my experience and discuss the role. Unfortunately David was 15 min late so I was on my way to work when he called. I answered when he began asking me why I wanted to work for him, and what drew me to the role. Frankly I was caught off guard there was no introductions, apology for his tardiness or pleasantries. He asked what my current position was then he asked if I want to make extra money so I was very confused to which he explained to role was part-time. I advised I am looking for full time opportunities only so it wasn't a fit and sent him an email once I got to work. The whole experience was less than 5 minutes long. He wrote back an insulting message which was unnecessary.
