Star Industries interview questions

I had multiple conversations with HR and a 2 hour conversation with management. I was led to believe I was strongly being considered. They emailed me a personality test the next day and I sent them references. An entire month has went by and I’m just sending follow up emails to force them to be professional and tell me I did not get the job. A one week work closure during Christmas is their only excuse. It is extremely unprofessional to ghost someone who came in person for an interview.
