It is commonplace to hear business leaders talk about their employees being the most valuable asset they possess. That being said, the effort we put into selecting them needs to be at the highest level. Interviewing is a skill that needs to be acquired ideally via teaching. To that end, strongly consider providing your management team with Interview Skills Training. Managers have some basic understanding for the most part about what to ask candidates for hire. What they often lack is a honed skill for how to ask questions, how to interpret responses and overall how to maximize the experience. Training will improve that skill.
