How do you feel about the potential for high turnover with entrepreneurial types, as it seems the general consensus is they will inevitably leave to start their own thing? How long do you expect someone to work for you before hiring them, getting them up to speed with your system, and integrating them into the company is a worthwhile investment?
When I get asked this in an interview, I always answer the same way: yes, I will probably go to the next gig faster than other employees. But I will get up to speed faster, and I will produce more output for the business itself in the time I'll spend in your company.
