When I went in for my interviews, I was really interested when I found out that the case I had just done was actually a real case that my interviewer had been a part of. After going through my own thought process with my interviewer, I was able to imagine what it would be like to face those kinds of problems every day, and it got me excited. Through the case interview process, I was able to see that my insights and assumptions are valuable tools in helping to solve complex client issues, even without a deep business background.
Entering into this kind of discussion with my interviewers was also a great way to get to know BCGers personally. The conversations I had and the connections I made was one of the reasons I decided to join BCG.
