I got this interview through the career services website at my college. The night before, we had an information session and dinner. At the information session they went through a practice "case study" that we would have in our interview. The case study seemed very simple, just percentages. The next day I had 2 interviews. First it was the case study. This case study was a simple concept, but they did not let you use a calculator. For me, since I am not a math major the math was impossible for me to figure out in my head (72% of 3450 -- for example) I had to write it out and did not do well. The executive who was administering this interview was extremely rude and cocky the entire time -- acting as if he already knew I "wasnt" good enough for the firm. Even though I don't know how doing simple math you can do with a calculator in your head qualifies anyone. The second interview was easy and with a nice HR person who asked typical resume based questions. It took them a long time to reply back and say no.
