I booked the Prep4Success Starter Package and definitely didn’t regret it. The coach that helped me prepare for my McKinsey interview was Robert. He provided me with very valuable insights on case cracking and PEI. It‘s especially during the final part of the interview preparation that P4S is the most valuable as it helps you get rid of those mistakes that case partners often don’t even notice. As well, Robert’s structure for PEI was exactly the way my interviewers at McKinsey wanted it to be.
