Applied through email. Was contacted 2-3 month later. Was invited for PST, it was very hard. Practice online a lot ! the week after I was contacted and been told that I passed the PST and interviews are within 2 weeks. Day one I had 4 interviews each one had a case and behavioral part (about 30 case -20 behavioral). Day two, I had one intense interview, it was only behavioral (no case). questions were tough. Mainly about leadership and communication/presentation skills.
