ServiceNow Customer Reference Manager interview questions

Contacted by HR (based in a different country from Hiring Manager and I) for a screening call, Interview was set-up but Hiring Manager didn't turn up. Process was then passed on to HR in the country the position is based in. Multiple rounds with Hiring Manager, other local teams I'll be working with. HR generally contacted me only to arrange for interviews, but did not provide much information about the interview process or rounds, how many other candidates there were and what to prepare for the interview. Overall, interviews went quite well. However, the communication from HR to candidates on their progress could be improved. Received only an automated rejection despite going through multiple rounds of interviews, and constructive feedback provided.
