BlackRock Project Manager interview questions

Applied online, after about a week they sent an email asking a bunch of questions which are normally covered in a call with the hiring manager. After a few weeks they replied to schedule an interview with the team. The hiring team was helpful but it was extremely difficult to schedule time for an interview, the team who was meant to interview was far from flexible and took long to reply. The interview was then held by a product marketing manager from the team for this role and another person whose role was unclear. Those two people asked me questions regarding my experiences for a full hour, however they were clearly reading questions from a list. They seemed to be quite annoyed having to interview me and were really rude, bad experience overall.
