I've been prepping heavily with friends from McKinsey and they've drilled in me the importance of going in depth explaining your framework/so-what's. Recently, however, I did a case with a BCG'er and they said that I was spending too much time explaining my framework's so-what's.
Is there an actual substantive difference in the depth you're supposed to go in your initial framework between McKinsey and Bain/BCG or is it more likely that I was just too verbose in this particular case?
