Kroll interview questions

I applied online for the role and heard back the same afternoon asking to arrange an interview and then I had three interviews over the next couple of weeks . The first was with Hr which was basic and easy. Second and third were with management which were progressively more challenging and formal. After doing well in the second interview, I was asked to do a third interview in the same week which was unusual but I took as a good sign. The third interview was more formal and challenging. I never heard back after the third interview from management or HR. I was completely ghosted by the company after completing three interviews with them.
