Look at it as a tool - not a punishment
Your goal as the owner of the company is ultimately to pad your wallet. Is it any wonder employees are EXACTLY THE SAME?
Employees are trading their time and talents in exchange for your capital. Just as your customers expect a good product or service in exchange for their money, employees expect you to compensate them fairly for their time/services. The idea here is that BOTH the employer and the employee get something they want. The thing is: no two employees value the same things. You should actually welcome these types of questions as part of the interview process because it exposes the corporate culture the potential employee is looking for. This is a big deal. Instead of looking at these questions as a burden on you, look at them as a window into them: their motivations, their concerns, etc. If you find that they want things that don't match well with your company this way, you've just saved yourself from hiring someone who isn't going to perform well at your company. Isn't that worth a little Q&A?
