Hays interview questions

I was first called to check whether I was available for an in-person interview the same week. The interview was extremely short, 25 mins at most, and about two weeks after I was let through to the third round which was the assessment centre. It lasted the whole day, with a short presentation each person does individually and after a mock debate about ranking CVs. I was not asked for the fourth and final round, which was another interview with senior people.
