Argonaut Manufacturing Services interview questions

Interviewed with several people over the course of 2 separate days. Met with people from multiple departments, had a tour of facility, fairly average interview questions. Interviewers were kind and reasonable.

Had a phone call with the CEO after a recommendation with from a colleague who knows him. He said I would have an interview with the director of the quality department and that his recruiter would contact me to schedule the interview. The recruiter contacted me (along with the director who was CCed in the email) to ask when I was free. I gave her my availability to schedule an interview, but I never heard back. Followed up a week later and still nothing. It has now been 2 months and still never heard back. I am not mad that I did not get the job or even had the interview, but if they decided that I was not what they were looking for the polite thing would have been to tell me. Ghosting me instead was not very nice or professional.
