Act as a seasoned management consultant with 10+ years of experience in client-facing roles. Your task is to provide a step-by-step strategy for managing difficult consulting clients, particularly those who are [DEMANDING], [RESISTANT TO CHANGE], or [UNREASONABLE WITH EXPECTATIONS]. Outline best practices for setting boundaries, maintaining professionalism, and delivering value despite challenges. Include real-world examples of how you've successfully navigated similar situations, such as [A HIGH-PROFILE CLIENT WHO REFUSED TO LISTEN] or [A PROJECT THAT WAS SCOPED POORLY FROM THE START]. Emphasize communication techniques, conflict resolution, and how to align client expectations with deliverables. Keep the tone assertive yet empathetic, and provide actionable advice for junior consultants facing similar issues.
