McKinsey has 6 case examples on their website, I watched 2 mock interview videos provided by McKinsey and today I had a practice interview with a McKinsey consultant. All of these cases were structured alike: a lot of information in the beginning, 3 main parts / questions to each case, 1 quantitative question. A lot of brainstorming and structure required, no endless calculations required. Mostly, they provided all the information needed to solve the case, sometimes you had to ask for specific missing data. I thought, they were all really managable.
BUT: Here on preplounge are so many cases that are labeled "McKinsey-Style" that are nothing like that. You need to know specific formulas or there are endless calculations in every question, or you have to ask for a lot of data yourself and figure out your way. Is this really something that could await me in my interview next week? Should I prepare for that or go with what I've seen so far "directly from the source"?
Any insight would be much appreciated :)
