Integra Technologies (KS) Software Engineer interview questions

Shortly after applying I was contacted via email and was requested to schedule an interview. The interview was conducted a week later and I met with the hiring manager and IT Director. They were both personable and professional. I felt the interview went went, it took about an hour and a half and consisted of multiple scenario based questions (ex: how I would handle if a project deadline needed to be changed.) I was also able to ask my questions and I felt they were answered transparently and thoroughly. There was a SQL based knowledge test given at the end of the interview covering multiple join statements. I was also given a tour of the plant and was able to chat and ask additional questions to the hiring manager. Before I left I was asked if 'X' specific start date works for me, I confirmed and let him know I was looking forward to hearing back from them. After 2.5 weeks I still had not heard back from them so I sent a follow up email politely asking if the role had been filled and confirming my interest in the position. I never received a response. Very odd hiring practice approach to completely ghost candidates. The job still appears to be available after being posted for 30+ days.
