IQVIA Manager interview questions

Several interviews face to face very positive and engaging. Questions asked related to the proposed position where I needed to show I had the capacity to take on the role . They used the STAR approach which was easy to answer to

Received email requesting phone screen after applying on corporate website. Scheduled phone screen with recruiter, but was stood me up with no apology or explanation. After sending email the what happened email finally received response a few days later. Phone screen was informational, not a real interview. Was then moved forward for phone interview with hiring manager, but found him completely disinterested and he abruptly ended call. I’ve never interviewed with a company that was so disrespectful.
