Dave Magrogan Group interview questions

I applied online, that same day I received an email back to complete a graphic design/marketing project challenge that included many different parts, which was pretty time consuming. After spending a few days of time and true effort on these projects, I submitted them to the HR person that had originally contacted me. I was then asked to come in for an interview. When I arrived for my interview, I waited about a half an hour for my interviewers, which I was not too happy about but I understood they were busy people (they seemed under staffed for the size of their business). During my interview, my portfolio was skimmed over very briefly and only one part of the extensive project they had asked me to complete was reviewed, also quickly without much interest. They talked about the company, but never really explained anything about the position until I asked. The interview lasted about 15 minutes. Overall, I felt they were very rude and disrespectful.
