I originally wasn't even considering consulting as an option after graduation, but after going to their info session a week prior to the interview, I was intrigued and thought, why not? First round was held on campus: 3 back to back case interviews. Even though the recruiter said that you can't really prepare for the case interviews like a MBB case...(I thought that comment was so not true), I'd say you can. Personally, I was wholly unprepared for the case interviews, and since I'm quite unfamiliar with business jargon, it was difficult to understand parts of the question, let alone problem-solve your way through them. If you're not a Business major/minor, I'd recommend googling some basic business terms before going in. Some of the MBB case prep material out there on the web is very detailed, and I wish I had access to them prior to my interview (i.e. Victor Cheng's website)
As for interview specifics: the first interviewer had never conducted an interview before, so although he wasn't sticking to the time limit, he was very nice. The question related to analyzing stock prices. The second case was about goodwill and building the company's brand, and the third case involved calculating profit margins. (I didn't even know what profit margins were before that day.)
All in all, no surprise that I didn't make the cut. Mediocre experience overall: interviewers were pretty intimidating except for the first one. Third interviewer seemed to be visibly bored with me, and ready to end the process.
