Deloitte 2nd round - any advice?

I'm through to 2nd round of interviews with Deloitte consulting. All they've told me is that I will do a presentation, a written exercise, a group exercise and another interview. Any more detailed information regarding what to expect in these exercises and how best to prepare for the day would be hugely appreciated, as it will be my first 2nd round.

Alex,

Congratulations on getting through. I too have managed to get throuhg to my first second round - rather relieved. Best of luck on the day and hopefully the community here will give us some helpful pointers!

It's all about how well you think on your feet. Don't obsess and you will do fine.
