we had a campus event with McKinsey about a week ago, and I had lots of great chats with the consultants during the event. Now one of them has called me yesterday, encouraging me to hand in a formal application via him. He suggested that this way, I would almost certainly get an interview invitation. As great as this sounds - the thing is that I have not really prepared for consulting interviews until now, and I am a bit concerned whether there will be enough time for me to get ready until the interview (if I hand in my application now). So I wonder whether it is a risk to delay my application by a couple of weeks? Also, how should I best prepare? Should I also aplly to other consultancies for practicing purposes?
