In my opinion, the questions seemed more like a consultation of ideas more than briefly covering several topics as you would expect in most interviews. Almost like fishing for ideas! Having received no feedback at all, I have since emailed the HR department asking for some type of closer, explaining that despite giving 2 hours of my time, the first of which was a gruelling assessment, not including the time it took to travel and the expense incurred to me in petrol and pay and display parking, receiving not so much as a thank you for my time I find both unprofessional and on a personal level extremely rude and insulting.
