Hi there,

It is difficult to provide specific tips without seeing you in action, but in general:

1. PEI tips

1. Understand the difference between, leadership, impact and drive areas. You can find their differences here: https://www.preplounge.com/en/consulting-forum/mckinsey-pei-difference-drive-and-personal-impact-918
2. Identify good stories for each area. Ideally you want to have at least two stories for each dimension.
3. Use a structure for your story. A possible model is the STARR one (Situation, Task, Action, Rational for Action, Results)
4. Identify for each story one sentence clarifying what the story is about and start with it. Think of it as the title of an article.
5. Practice live, collect feedback from people listening to you, reiterate until you get fluent and persuasive

2a. Communication tips

1. Present the first level, then the second level: “So given the goal XXX, I think we could look at 3 main areas: first ABC, second DEF, third GHI. If ok with you I would like to go deeper into each”
2. Use numbers/clear bullets when presenting levels: “In the first area I would like to look at the following: First…, Second..., Finally..."

2b. Case structure improvement

This is a very broad topic and it would be useful if you could detail the feedback you received a bit more to provide an answer.

Hope this helps,

Francesco
