Creating Positive Futures interview questions

I completed a video interview, 4 separate interviews/ conversations with staff members and the CEO of the company, plus a writing assignment. After contacting my references in February (all of whom told me that they had great conversations and that I was perfect for the job) I did not hear anything back. I emailed several times and kept getting the run around until I received an email in APRIL saying I didn't get the job. I responded asking why, and received no response. I was very excited about this position and now I am extremely disappointed in this company and their unprofessionalism and lack of communication when hiring.
