When I first started out as a business leader, I worked alone from a home office. If I needed help, I asked my brothers or hired a freelancer I found online. While a few freelancers turned into long-term contractors, I didn’t have any full-time employees.

But after a few years, it became clear that I needed to open a brick-and-mortar office to keep up with my customers’ demands. A few of my contractors came on board full-time, ready to engage with a team face-to-face. Others, however, weren’t willing to give up the freelancing lifestyle.

I knew I couldn’t stick with freelancers forever—it was time to start interviewing candidates. I’ve come a long way from spending my 9-to-5 at home, and I’ve seen it all in the hiring process.

Over the years, I’ve found that my best employees all showed the same trait in their very first interview: a deep desire to succeed.
