You need to be more structured - set out what you want - interview them properly - choose a location if you don't want to do it at home like a cafe - always get a cv ( how can you question them if you don't have some paperwork to look through ) see how they dress ( does not need to be a suit - smart casual ) do they ask you questions, are they interested in what you have to say ? - did they turn up on time ?
Taking on an employee is THE biggest step in your biz - make it count, take your time and choose correctly
Ultimately the wrong person could steal from you, ruin your reputation etc.... DONT SKIMP!
Take your time, also you need to be a manager, be professional, no swearing, no losing your temper, no bitching be constructive - expect most people not to be as dedicated as you are, they need rules and regs for everything....
Now put yourself in their shoes - your offering very little security, a bit of cash in hand/ minimum hours or wages and not much else ( I certainly wouldn't be enthusiastic to work for you ) an employee is a prized asset - treat them as such
