I had a first round interview with the hiring manager, which went great. I quickly got an update from the recruiter that I was being put through to a final round, with great feedback. That was the last update my recruiter got from the hiring manager, full on ghost mode. It just isn't good enough, the job market is hard enough as it is, to have people out there, string a long people. It's not too hard to expect people to be up front, and timely in responses.
