LSEG (London Stock Exchange Group) Risk Management interview questions

It was meant to be 4 round interview process initially with the hiring manager and then with the team and then the CXO/Director for the team. Had 3 rounds of interview which were with very polite and nice people, however they just stopped responding. After nearly 3 hours of interviews, I found this extremely frustrating. Really disappointed when someone has given the time to go through the process you atleast tell them what is going on or if you are no longer hiring. HR and hiring manager never bothered to respond.
