WTW Corporate Risk and Broking Graduate Development Programmer interview questions

Had to do a video interview first. then two weeks later I got a call asking to come to an Assessment Centre. There were 4 grads and 4 interns at the AC. I was put in the intern group, had 4 one to one interviews and one group exercise I was made to feel at ease the whole time, I was nervous for the group exercise as it was first. But the staff are lovely and I literally got to ask endless questions
