I used to have a little cell phone repair business and it had a website, should I mention the website when I bring up the business? It wasn't an official business though more of a personal hobby/experiment.
However, would it be a good or bad idea to put the website address in?
BTW this is for a school that ONLY does WRITTEN interviews.
Did you actually have to register this business for tax purposes? If so, I would mention that as part of your employment history.
If you only did it as a hobby, having a website is irrelevant. A website is no different than handing out some paper advertisement for a product that you might be selling as a hobby.
It your "business" crossed the threshold where you would have to report the business for tax purposes, than yes - it should be mentioned as part of your history. Otherwise, it might be good to mention that you did this as a hobby and made a little extra money from it at one time.
As a personal example: I am fascinated by social insects such as ants and bees. I actually do personal scientific research on ant colonies, and I currently facilitate the growth of 6 ant colonies under observation. I became fairly good at building the habitats that they live in out of stone. I ended up advertising on a website that I am involved in, and I was selling insect habitats to some of the members. This "business" did not cross the threshold of having to report it for tax purposes, so I simply claim it as a hobby that I occasionally make money from.
Oh yea! I also had a "business" where I was selling "online gold" to people that play online multiplayer games... haha! it was fun, and I made a lot of money.. I did have to claim that. So, I add that as part of my employment history as a self started business.
Good luck in your interview!
