Went through 2 rounds of 2 case interviews, each following the same pattern, 10mins to talk about yourself, 50mins to go through a case. Very typical format. Cases were not overly difficult but still required to be quick on your feet, especially with calculations that could be quite heavy. Something less typical though was the not quite friendly attitude. People were somewhat patronizing, arrogant, old school in the sense they were almost bragging about doing long hours (70-80hrs a week). I've been in consulting for a long time. My opinion is that if you do such long hours, every single week, then there is something wrong somewhere. Projects might be understaffed or suffer some inefficiencies. Modern companies aim for a reasonable work/life balance. They don't. They also want candidates dying to join them, having the firm in the highest regard. They seem to forget that here in north american, they have nowhere near the reputation they have in Germany or France.
