KPMG launch pad assessment centre

Hello,
I was wondering if anyone who had an offer with KPMG could give me tips for the launch pad assessment centre.
How many people does it consist of, how many people are in the group, what tasks are there, group task activity, interviews etc? I would like good tips especially for the group task and the interview (what kind of questions were there etc)
What time does it roughly start and end. Also, when they assess whether you're suitable, do they select you from the group you're in or look at everyone within the launch pad. How do they assess you etc?
