For broad cases like PE invetment, M&A, Market Entry etc. what level of details should be included in the initial structure shown to the interviewer. Let's say it's PE invetment case should I include all the buckets (PE characteritics, market structure , target company, valuation, way to improve operations, profitability, revenue, multiple etc.) with 5-6 points under each bucket? My worry is such broad structure looks generic and rehearsed with lack of clarity of purpose plus it takes almost 7-8 min to walk through it, on the other hand if I try to use some customization there is a probability that I might miss out on most crucial part of the case.
