RTX Vice President interview questions

Referred by an employee for a new role in development and was contacted by a corporate recruiter who did an initial phone screen which lasted about 30 minutes. Questions included strong probe on my salary requirements and explaining the job had a VP title with Director level pay which did not make the role as attractive. Recruiter then sent the job description a few days later and was a bit frantic to schedule a phone interview with the hiring manager and HR which was done within a few days. Sixty minute phone interview with the hiring manager was a bit one sided, acronym filled and difficult to get a word in edge wise but I was able to ask some questions which were answered tersely and with limited detail. HR person was silent and didn’t ask any questions or participate in the discussion. An hour after the call the recruiter requested email feedback on how it went and I provided my input noting I was interested to continue the discussion. That was the last I have heard from the organization, a follow-up email and phone call to the recruiter went unacknowledged as well as an email to the hiring manager. I found this very unprofessional, especially for a VP level position.
