Online application (includes 7 competency questions)-->A 20-minute phone interview-->A half-day assessment center which contains one-to-one interview, group case study and individual case study. The case study was the hardest part. It included 3 sub-cases and lots of reading material and we were given 45 minutes to come up with solutions to the 3 cases. It was not department-specific. I applied for supply chain but received cases related to marketing as well.
