Highmark Wholecare interview questions

What happened to professional courtesy? As a candidate, there are certain expectations recruiters and companies expect. Why should I not expect the same courtesy when going through the interview/ hiring process? Applied online. 3 days later received invitation to complete an online assessment. 3 weeks after that I received an email to schedule first interview. Then they rescheduled for the following week. I was supposed to interview with the director but was advised he was busy and a manager stepped in 5 mins. beforehand. Manager is very knowledgeable and seems like a really great guy. Interview went amazingly well from start to finish. Everything discussed seemed to be an ideal fit. I received very positive feedback during the hr long process. -You're exactly what we're looking for- -Your experience is a perfect match for our team- I stated I felt the same and was excited for the opportunity. He advised that they were making a decision within a week or two and I would definitely hear back either way. Then nothing, GHOSTED. A week later I sent a follow up email to the recruiter, no response Waited another week and left the recruiter a vm, no return call. Yet, my online profile still shows I'm an active candidate ( now 9 weeks after applying) Why do companies think this is an acceptable practice? Either make an offer or don't... Sincerely, FRUSTRATED CANDIDATES EVERYWHERE
