As an intern, your interactions with senior executives (both within the firm and at the client) were likely limited and highly supervised. You may have observed more experienced consultants presenting to clients, but had few opportunities to do so yourself. Your focus was primarily on producing good work, with less emphasis on how you presented yourself and your ideas.
As a full-time consultant, developing a strong executive presence becomes crucial. You'll be expected to convey confidence, credibility, and competence, even in high-pressure situations with senior clients. Executive presence isn't just about appearances; it's about commanding respect, inspiring confidence, and effectively influencing decision-makers. This skill becomes increasingly important as you progress in your consulting career.
