We ask professional services personnel to perform a broad spectrum of tasks, regardless of their written job description. It is an essential skill to deliver a successful presentation, whether to a small working group, boardroom or an auditorium. As a hiring manager, you may have asked questions about applicants' presentation skills and techniques. You may even have gone so far as to ask for them to make a presentation to you and a colleague as part of the hiring process. In doing so, you may confirm that they can stand upright, narrate bullet points clearly, and advance slides on time.
