Jamf Enterprise Support Engineer interview questions

Everything seemed standard, interview with HR, interview with hiring manager and then interview with the enterprise Support team. All interviews went great and I was told I would hear something soon. Instead I've been ghosted by HR and hiring manager. I've reached out multiple times just to hear back even if i didnt receive the position at reply to the candidate who you had 3 interviews with and was very interested in the opportunity. The lack of communication was terrible. The interview i did get with hiring manager was only told to me hours before and i had to reach out to HR asking if they heard back. Only to be told oh yes they have availability today if you are available. Thank goodness i reached out or i wouldnt have known about it. I'll never understand why someone can't take 30 seconds to reply "sorry the position has been filled"
