I applied in early November 2017. Received offer within the 2nd week of Feb 2018.
4 stages of Interview :
1. Online Application and Screening
2. Online Test by Hiring Partner
3. Assesment Day with other shortlisted applicants - Group case study, individual presentation, and 1 on 1 interview. 1 on 1 interview was with the country HR manager. Interview was competency based.
4. Final interview with regional managers/directors . A more personal "get to know you" interview. Fairly informal
