IQVIA Associate Clinical Project Manager interview questions

I initially applied online and was invited to an screening telephone interview with HR (talent recruiter) the same week. Interview initially went really and I felt positive about the experience. I was told that her college would contact me next week after speaking with the hiring manager to schedule a further interview. I was asked for my availability for future calls and provided a range of dates, and offered to look further ahead into my calendar if needed. Nearly 2 months later, no response. I have followed up twice with the talent recruiter I spoke to during the screening call, and have been ignored on both occasions. Highly unprofessional, another example of "professional ghosting".
