Case Study is a must for marketing internship roles since there are so many candidates and they really want to get the "brightest" ones. We weren't divided in groups, instead we gathered all together with 2 marketing assistants in a room and did a brain storming session, The most important thing here is that you need to step up, and speak out.

It was very good and professional. They asked standard questions, and I feel like I did alright, but the industry is so competitive nowadays. Good luck if you're interviewing with them!
