Andersen interview questions

I had about 4 interviews, make it 6 including lunch. That is way too many, it took over my entire day. Not only were they long, but the interviewers themselves were rude and unwelcoming. right when walked into the interview room, the lady asked, "why are your grades so bad?" I had a C in accounting and the rest were either A's or B's. My second interview, the man literally yawned in my face. If you're seriously that bored, why are you there? On a somewhat positive note, they did take us out to lunch at a nice restaurant and reimbursed us for our traveling expenses.
