Did a Hireview interview then a few months later invited to the AC. AC was just interviews. No group work or case study. Then if they liked you they would do a final round of interviews ( not always the case)

Process was three rounds. First two were back to back 30 minute interviews w VPs. Conversational in nature. 2nd was a 30 minute call with two MDs/Bankers. 3rd was double checking your interest in the role
