As an intern, your interaction with clients was likely limited and closely supervised. You might have attended client meetings, but probably didn't have significant responsibilities in managing client relationships.
As a full-time consultant, building and maintaining strong client relationships becomes a critical part of your role. It's not just about delivering good work; it's about becoming a trusted advisor to your clients. Strong client relationships are crucial for project success, lead to repeat business for your firm, and can significantly impact your career progression.
