On the outside, blowing your horn on your resume about starting and running your own business from scratch for the past three years may seem like a good idea, but when you look deeper, it may not be such a good idea.
Companies usually shy away from recent business owners because they question whether someone who has so recently tasted entrepreneurial fruits will be committed to the job they have open. They fear that you are simply using the position to bridge your business financially, or that you will fly the coup at the first new business opportunity to come along. Either way, the company would stand to lose time and costs in training someone the are not sure will be there one year from now.
When it comes to your resume, downplay the ownership by using an appropriate title from one of the many hats that you wear. Discuss the business ownership in the interview, where you can alleviate fears and support your position.
