Amplify interview questions

I had a current employee submit my resume but never heard anything from them. Then about 6 months later I submitted my resume online and got an offer within a week. The interviews consisted of a 1 hour phone interview followed by a 45 minute group interview.

I reached out to one contact I had through a friend. She and I exchanged messages for about four weeks. It always took her several days, more than a week often to return my message or move the process forward. It started with a phone interview and then she wanted to look over my writing samples. Then I waited and waited. The entire time it felt like pulling teeth. Finally I got an interview with the President of that division. It took weeks to arrange. Then they begged off at the last minute. I finally sat down with him and the interview was okay, not great. He seemed to want me to come up with a solution within a minute for something that had been troubling him for days. Then he expressed doubt about my ability to get all the writing done. At the end I thought I made my case. He said he would get back to me in about a week. Two weeks later, nothing. So I called. His assistant said I should call back. When I did and on subsequent calls, they screened me out and I left at least 2 voicemails and 3 unanswered emails, before finally going back to my original contact to ask why they were avoiding me. Just awful treatment. And then they said they couldn't find a place for me. I just don't understand why people treat other people so badly.
