IQVIA Entry Level ACE CRA interview questions

The first introductory interview (.5 hours) over the phone was conducted in early May. Three days later, an hour long interview with the Line Manager in Dallas, TX. Laid back interviews. I didn't hear anything from them for a very long time (close to a month). Keep in mind, they were scheduling training for those they liked first weeks of July so they were entertaining me prematurely. Finally received an email back from another recruiter asking to schedule a video conference interview -- for the next day. I was unable to oblige for the time scheduled because I had an internship interview scheduled weeks before for my Master's program and thus the Quintiles interview was rescheduled to a later time. No new link for the video conference chat and when it came time to interview, my video chat link was a broken link despite the manager interviewing trying to resend -- I know the program worked because I used the test link prior to the interview. I was told by this manager that I would hear back in the next few days. That turned to a 11 days even though the recruiter said I would hear back by the end of the week. I also did NOT get a phone call explaining why I was not selected for the position. I emailed the recruiter back asking why I received an email and not a phone call with an explanation. Especially given that I had carved out pieces of my day for their multiple interviews. I have a feeling that the manager didn't particularly care for me and that maybe I was a threat to her position because I didn't get any of the tough 1572, GCP/ICH, regulatory/source doc questions that others have indicated they received. I am disheartened. Sending an email is not the most professional way to communicate to someone that they did not get a position. Pick up the phone and be polite in informing your candidates on why they didn't fit your position!! And please do it in a timely manner.
