Cisco AS Project Manager interview questions

I'm an internal candidate interviewing for a Project Manager role on the TA team. I applied for the role 49 days ago through Cisco's internal job portal. After applying, I directly reached out to the recruiter 3 times before getting a response over a week later. My current manager even reached out to the recruiter giving their endorsement for my candidacy. Three weeks later I had my interview with the hiring manager who was very nice and informative. I felt like it went well, she explained her expectations of the role and goals for the team and then I shared my experience and why I was interested in the opportunity. The hiring manager said she'd get back to me mid-week which was pleasantly surprising. Over 3 weeks later and I still haven't heard from her. I've followed up with the hiring manager 3 times via email and radio silence. I can clearly see her calendar and that she's active on WebEx teams. I've followed up with the recruiter 3 times as well directly on WebEx teams and no response. I work with Talent Acquisition leaders and Recruiting team members on a daily basis and they take pride in candidate experience. This has been the opposite of good candidate experience, especially as an internal candidate. I was excited to be interviewing for this role, now I'm second guessing my interest in the role due to the lack of communication and common curtesy. Leaving a candidate in the dark in regards to their candidacy is simply unprofessional.
