1. 3 minutes phone interview on why you chose this company. The main rationale is probably to fix your availability for the assessment center which will only be a few days later.
2. During the AC, you will be in a group of 5. There are 2 cases. First one is an analysis of one particular product and some supporting statistics. Read and create a marketing plan to give a 5 mind presentation to the panel within 15 minutes.
Next is a seemingly simple but yet, challenging accounting question. As a group, you all have to suggest what needs to be done to achieve the KPI the question is asking for. 10 minutes for the task.
3. Final interview are mostly questions from your resume, and your working experience. They are mainly interested in aligning your experience and see if you are suited for the job. They are all really friendly, not many particularly hard questions.
