i recently attended a pre-first round webinar for McKinsey Dubai hosted by a McKinsey consultant. However, within the webinar, he mentioned that for the PEI section, the interviewer is more likely to choose a random line on my CV and then ask me to speak about it for 15-20 minutes, and while speaking I will have to demonstrate 2-3 of the PEI qualities within the story.
This is very different from the online sources and guidance from other webinars and the recruiter. In terms of preparation - should I focus on generating 2-3 good stories which may/may not be on my CV per PEI quality? Or should I make sure I have a 20 minute story for every CV point.
Would very much appreciate any of the guidance or tips from this community, as I am currently quite stressed and confused.
