OP says he is starting a computer business which is fine for membership. Even if hes working full time elsewhere, most people here probably started after hours too.
I flip-flop back and forth between full-time employment, to doing big projects as a team, to doing my own side-projects and consulting... to teaching at a university on the side.
The reason I don't settle down as a business is that it is so much work to advertise and find the right projects. I always have to bid, meet with people, write proposals, etc... It would be easier to open a brick 'n mortar store letting people bring their computers to me, but that is no longer my specific area of interest. I really don't want to fix Mr. Smith's desktop where he installed adware, diagnose another bad hard drive for Janet, or Install windows for Phillip.
In networking, nobody brings their equipment to you to return and pick the equipment up configured.
For this reason, I always end up back at full-time employment with more side-work than I can handle.
That said, by the very definition I am not a pizza-tech for doing side-work because people look for me via word-of-mouth, LinkedIn, and other reputable meetings i.e. chambers meetings.
Q: What makes you a professional not DIY ? A: You derive your primary source of income in Tech

Anyway, to the Op, don't worry about it. This is the type of test I would give a systems administrator NOT a help-desk technician. I would be more interested inf finding out that you are well-rounded and know a little about a lot such that you could classify tickets correctly.
My questions would deal with how you prioritize tasks and handle people.
