Referred by internal candidate before actually applying. HR called me out of the blue a few days after I had sent my CV to my contact. I spoke with HR for approximately 30 minutes however it would have been nice to have something scheduled as I was out of the house and caught off guard. The HR call went well and I then had an interview set up with the hiring manager the next day. A week and a half later I had nine half hour interviews over the course of three days. I also gave a 45 minute presentation to the individuals with whom I had interviewed. Three days after my final interviews and presentation I contacted HR as I had to respond to an offer I had from another company (I had informed HR of this offer when we met). No response. Four weeks after my final interviews HR called me. I could not answer my phone so she left me a message asking me to call her back. I called her back a half hour later and it went to her voice mail. Three days later I called her back and left her another message. It's been two weeks since she left me the message asking that I call her back and still no response. To be ghosted after so many interviews and a 45 minute presentation is both unprofessional and disappointing.
