great question, that’s actually something many candidates confuse. I have provided a description of the different areas below, together with what to focus on:
1) Personal Impact is mainly based on persuading someone about doing/not doing something. Questions include:
- Tell me about a time that you persuaded your boss to go along with an idea you had.
- Tell me about a difficult situation where you had to rely on your communication skills.
Here you want to emphasize your influence on someone else, usually in disagreement with you.
2) Entrepreneurial Drive is about starting and implementing something overcoming major difficulties. Examples include:
- What was a situation where you set a major goal and been able to achieve it?
- What has been your major accomplishment so far?
Here you want to emphasize the achievement you reached and the process that led you there.
3) Just to complete the analysis: Leadership is about leading a whole team in challenging situation and team management skills. Questions include:
- Give me an example of a time when you lead a group.
- What are some key lessons you have learned about motivating people?
Here you want to emphasize how you overcome a difficult situation leading a team (not necessarily as the official leader).
EDIT: Since 2020 McKinsey started to call the Leadership dimension "Inclusive Leadership". The dimension is the same as before, but now concerns a diverse team instead of a team only.
Many candidates tend actually to confuse leadership and personal impact. In both you deal with people, but while in the first you are leading a team, in the second you are actually influencing someone else (not necessarily a team). In the first case you then end with a team result, in the second with your own specific result.
Hope this helps,
