The interview started in a group setting where you and about 4 others work on a PowerPoint presentation. I was then interviewed by a panel of three people in a separate room for about 30 minutes. The questions were pretty general and more focused on more background and interest in the company. The presentation was a case study analysis on how to address a company's organizational needs, followed by Q&A by the interview team. Overall, it was about 3 to 4 hours, but it went pretty smoothly.
