What does this involve?thanks.

A set of questions and logic problems both written and verbal.

I did one assessment at Atos for the Procurement advisory team.If this is the one you are going for then there is 1hr experience interview with HR and then a business case to prepare in 45 mins and to present in 15mins.I could choose 3 topics when I did mine:1- Procurement Outsourcing2- Low cost country sourcing3- Stakeholder managementGood luckN
