This question aims to determine what gives you job satisfaction and whether McKinsey and Company can meet your expectations. Yet the nuance of this question suggests something more. It also aims to determine whether you are satisfied with your career. Some choose their career and wish they'd taken a different path. Others may stumble into their field and feel trapped. Any clues into your satisfaction with your career could inform your interviewer whether you are leaving your job to look for another, hoping you'll find greater career satisfaction with another company elsewhere. However, in this scenario, the grass is rarely greener on the other side.

Posting a job vacancy, interviewing, hiring and onboarding is expensive, and longevity is desired. A candidate's job or career satisfaction plays a significant factor in whether they are dedicated. Therefore, your interviewer needs to ensure the candidates they consider will find a satisfying career with McKinsey and Company and stay a long time. Share what you love about the career path you've chosen and the direction you desire to take your career. Exhibit your enthusiasm and passion, and be specific. To say you like to 'help people' won't be enough.
