Mars European Procurement interview questions

Applied online and had to complete many tests Then had half an hour skype interview which was quite repetitive in their questioning Was invited to an overnight assessment process. There were 8 of us. Very fancy dinner provided with 4 employees who we spoke to informally and then the next day invovled essay/case study for an hour, individual presentation, grou work and an individual interview. It was very intense and far too draining.
