I got the virtual cards case study. The interviewer asked about background and small talk for the first 2 mins and the rest 40 mins were just about the case. How can they improve it? What value does it bring? How is the costs calculated for Capital one? What technical components do you need to think off for the screen they show you. What other improvements could you make? How would this information show up in the database? Etc etc. I do not think it was too crazy, they are basically looking for a work environment fit at this stage.
