EY Intern interview questions

This was for the combined internship at EY Advisory and TAS. Started with online tests, thereafter called to interview at their office. We were 20-30 people there at the same time interviewing for the position. Before the interview consultants gave a presentation about EY. The interview started with a case. You were left alone in a room for 20 minutes or so with information about the case. During this time you needed to solve the case and prepare a presentation. Then two consultants came that listened to your presentation and asked follow up questions about the case. Thereafter two other consultants came in and did a general interview.
