Assessment centre was very friendly. Consisted of a group exercise, presentation and interview. The group exercise was about building a bridge using paper, paper plates, plastic cups and tape. There's an audience of about 10 people watching this at all times. They replied within two weeks. It was very relaxed and chilled. But they did tend to interview non engineering students for a lot of engineering positions, which is a bit weird. Also my feedback was that I used too much "engineering language" when building the bridge, and some staff didn't understand that.
