This question is reserved for the person who meets your requirements. Ask for at least three - two professional and one personal. When they are provided, call. When you make contact, tell the person exactly why you want to hire the worker. Assure the individual you contact that anything he or she says will be kept confidential. Regardless of how you feel about the candidate (impressed, excited, etc.), you must follow up and check references. It could make the difference between finding a good, healthy situation and one wrought with problems.
