Got word from Mckinsey last week that I proceeded to the 1st Round Interviews, which is scheduled to be somewhere in end September (dates haven't been confirmed, the recruiter mentioned that's when they are aiming to hold it). I'm still very much at the beginner level, relatively new to case frameworks and the whole process. Based on my research here, most recommend at least a month of active preparation for Round 1 interviews. This leads me to believe that perhaps 2-3 weeks won't be enough and maybe need a bit more time to help prepare.
Would it be weird or looked upon negatively if I ask to reschedule the interview for a week/week and a half? I will probably be honest and state that I want to be at my best for this opportunity - which comes by once in a while. Would anyone also recommend the best way to help gather some people to assist in the case prep?
Thanks so much! Love this community and your contribution.
