Judgemet at virgin ADs ARE based on your interaction and talking to thee people. Is so is very much so! The recruits advised me and all of us that got through to the interviews. That they watch you the moment you set foot on the property. How up relate, interact, present yourself, speak etc. and all how you do that with other people and deal with situations.
That is why they do not necessarily do a group activity. But they could not stress more to me that the main part is team work and cooperation. I stayed back to talk to the assessors as I had a great day and they told us all this.
So I wouldn't go as far and say virgin dont score on that at all. Like you said it is interaction, but it's not like it's just you alone at all when you look at the big picture.
In my opinion The day was very fun, recruiters were SO SO nice and it was relaxed. I wast even one bit nervous but that's just me.
