I got a case interview via phone for 30 minutes, lots of data and concepts. It was pretty hard for me ,especially international students like me to grasp the very idea whether it is 15 or 50, and also through the process, i made some basically math mistakes,so that is why i think i will fail......I would prefer one-on-one case interview

Met at on-campus career fair and submitted resume. Resume was sufficient to earn a first-round interview on my university's campus. Passed that and was invited to an interview at their Richmond, Virginia location. They paid for my flight there and back and my meals. The interview day at Richmond consisted of 3 interviews - 2 case interviews and 1 behavioral. The behavioral was just like any other job interview. The case interviews consisted of math problems involving various topics from credit card rates to life insurance. The interviewer is there to help you through the problem with any questions, but it is important to keep your work organized and not get stuck in one area.
