HBK Engineering Project Coordinator interview questions

I was reached out to for a phone interview by the an HR person for the Project Coordinator role. After a short conversation basically talking about the position and my experience working with clients she wanted me to come in for an in-person interview. I came into the office about a week later for the in-person interview with again the HR person and then the and one of the department heads. It was a pretty laid back interview asking about relevant experience and giving examples of current programs I use, interview lasted about 30 minutes. The HR person then said she would get back to me by the end of the week. The end of the week comes and I don't hear anything from her. I wait a few more days then I send a follow up email to her mentioning I still had not heard anything and I would like to hear some feedback from my interview. It has now been almost a month and I STILL have not heard anything. So I was completely ghosted. I'm an adult I can handle hearing if I did not get the job. I find the situation unprofessional and it shows a general lack of respect for other people's time.
