I have been self-employed for close to 30 years. I have had multiple businesses, some I stayed in for too long and some I may have quit earlier than I should. I am looking to spread some knowledge, but need specific questions so that I can answer them truthfully and show you what could have been done differently. Basically I want to use the knowledge I have gained to show you how not to do it.
Some people are good at interviews and make terrible employees, and some are terrible at interviews and make fantastic employees. I have my doubts that you can find out much from an interview other than are they on time and do they have the requisite knowledge.
