I have typically practiced candidate led style and recently started to practice interviewer led cases.

I'm concerned that if I practice both case format at the same tine, my ability to lead a case will be reduced. I sort of feel that once I have practiced interviewer led cases, I will naturally develop a habit of expecting interviewers to lead the case and guide me on specific topics they would want me to focus on. 

I'm worried that developing such a habit would impact my performance in a candidate led case interview. Any suggestions are appreciated. Should I avoid applying McKinsey and BCG/Bain at the same time, as it might be better to focus on one case format at a time?
