I have practiced candidate-led cases for a while (50+ cases), without specifically practicing any interviewer-led cases. I'd like to hear your advice on:
(1) Given that I have only practiced candidate-led cases, do I need to specifically practice interviewer-led cases if I apply for McKinsey? What would be some major points that I would need to specifically enhance / prepare for interviewer-led cases?
(2) Is it better to apply to McKinsey after interviewing with BCG and Bain, or is it okay to apply / prepare all 3 firms altogether at the same time? I feel that the 2 format each focuses on different aspects, so I am just cautious about whether I should apply to all 3 firms at the same time).
Thank you for your advice.
