Anglian Water Graduate/Trainee Modeler interview questions

It was relatively simple, I applied using my cv and cover letter, to be fair they responded quickly and I was invited to an interview in Peterborough. The interview was fairly simple, they gave me 10 minutes to talk about myself and then provided a diagram of an office with its community and I was asked where to build a car park. How it would affect the community. Was it worth building? After the interview I never heard from them.
