I just finished undergrad in Europe and have a couple interviews lined up with top consulting firms this month. I've thoroughly read through CIP, watched Victor Cheng's online videos, and listened to LOMS extensively. I've practiced with 20+ cases from old HBS and Sloan casebooks (this includes examples of cases from all of) and have done a couple cases via Prep Lounge. Also, I've given 20+ (as the interviewer) for a student-run consultancy.
Send me a PM, or leave a comment if you'd be up for practicing via Skype.
