ASDA interview questions

I was invited to a group interview with three other applicant. We fist had to fill out a coupe of documents with what hours we were available and where we would prefer to work in the store. Then we were told to find out everything about there person sitting next to us and then to tell the others in the group what we had found out !! Finally in our pairs we had to make a tower of some kind out of marshmallows and spaghetti and link it to Asda and then explain it to the other pair!! Finally we all had to do a individual interview, it wasn't really a interview just a chat, the only question he asked was why Asda .... He then offered me the job and said they would be in contact with a date for the induction within the week
