Hiring is risky and the process can be daunting. Look past impressive resumes with hard experiences into soft skills and who the candidates really are.
Ask open-ended questions to find out if your candidates possess the initiative to correct problems on their own, skills to make difficult decisions such as those counter to a personal bias and ability to apply their knowledge to new situations. Review their experience to find out how versatile and agile they are. Look for their demonstration of interests in your company and test their follow-through skills if it is possible.
It is important to make calling for references a priority and looking for recommendations.
