The process is relatively long, with up to seven stages. Stages 1 to 4 start with screening and focus on cultural fit and personality, as well as a quant part. Stage 5 is a phone interview + business case. It will take around 1h 30 minutes. First, you will answer questions in a strength interview format. Then, you will be given a case and 30min to prepared. Afterwards, you will have to present your solution via phone. Step 6 is an assessment center in which you will spend many hours doing individual and group activities. My recommendation, be mature, proactive, confident and oriented to the goal of each activity, think fast but be analytical. Finally, there is a panel interview to which I have been invited but not yet participated.
