ServiceNow Senior Project Manager interview questions

One basic HR screening where I was asked about my current role and a few questions on compensation. Then three rounds of interview where I was asked about my work and a case. After all rounds were done, the HR told me that my interview went well and the hiring manager liked my profile but they want to review other candidates and have put my candidature on hold which was disappointing and unexpected from a company like ServiceNow.

Basic HR screening with no feedback on the expectation on the next steps. HR kept on telling will need HM's input on most questions, so not much clarity on the role and expecations
